Roy Lichtenstein’s prints can carry signatures, dates, edition numbers, proof designations, blindstamps and workshop markings that vary considerably from one edition to another.
Many original Lichtenstein prints were signed, dated and numbered in pencil, while others include artist’s proofs (AP), printer’s proofs (PP) or additional workshop impressions outside the regular numbered edition.
The key is not whether a signature or edition number follows a single standard format, but whether the inscriptions and markings correspond with the documented characteristics of that specific print.
Expert review: by Robert Ubillus Adelman, Owner & Director of Masterworks Fine Art, with decades of experience buying, selling and evaluating original modern and contemporary prints.
1. How Did Roy Lichtenstein Sign His Prints?
Many Roy Lichtenstein prints were signed in pencil, frequently together with the date and edition number. Signature and numbering placement varies by edition.
For example, Modern Print, 1971, is documented with the edition number in pencil at lower left and the signature and date at lower right. Other editions place the number, signature and date together.
Collectors should therefore avoid judging a Lichtenstein print solely by comparing its signature with a generic signature example online. The signature and inscriptions should correspond with the documented edition.
2. Understanding Roy Lichtenstein Edition Numbers
A standard edition number is commonly written as a fraction.
For example:
24/100
A standard edition number is commonly written as a fraction. For example, 24/100 identifies impression 24 from a regular edition of 100.
The first number identifies the individual impression; the second indicates the size of the numbered edition.
Lichtenstein’s edition sizes vary considerably. Some prints were produced in editions of several hundred, while technically complex later works were issued in much smaller editions.
Always compare the edition number with the documented Corlett or RLCR entry for the specific work.
3. Does a Lower Edition Number Make a Lichtenstein Print More Valuable?
Generally, no.
An impression numbered 3/100 is not inherently more valuable than one numbered 83/100 simply because its edition number is lower. Both belong to the same edition unless there is a documented physical or historical distinction between them.
Image desirability, rarity, condition, provenance and collector demand generally have more influence on value than the numerical position within an edition.
4. Roy Lichtenstein Artist’s Proofs: AP
AP means Artist’s Proof.
Artist’s proofs exist outside the regular numbered edition and were traditionally retained for the artist or other purposes connected with producing the edition. Lichtenstein’s catalogue raisonné frequently records the number of AP impressions associated with a particular print.
For example, Imperfect Diptych 46 1/4" x 91 3/8", 1988, was produced in an edition of 45 plus 14 artist’s proofs; Phillips has documented an impression numbered AP 13/14.
An AP can be an authentic impression from the documented edition, but it is not automatically more valuable than a regular numbered impression simply because it is an artist’s proof.
5. Roy Lichtenstein Printer’s Proofs: PP
PP means Printer’s Proof.
Printer’s proofs were generally reserved for the printer or workshop responsible for producing the edition and can exist in much smaller quantities than the regular edition.
For example, Phillips has documented Sunshine Through the Clouds with an impression inscribed PP II, outside the regular edition of 60 and eleven artist’s proofs.
A printer’s proof may be scarce, but scarcity alone does not guarantee a higher value. The particular print, proof designation, condition, provenance and collector demand all matter.
6. Other Proof Designations on Roy Lichtenstein Prints
Lichtenstein editions can include several proof types beyond AP and PP. Depending on the edition, collectors may encounter designations such as RTP, PPI, PPII, GEL, C, SP or other workshop proofs.
The official catalogue for Modern Print, for example, documents:
- Edition of 200
- 15 AP
- 1 RTP
- 1 PPII
- 3 GEL
- 1 C
Proofs may also be numbered differently from the regular edition. Some Lichtenstein proofs use Roman numerals or letters rather than conventional Arabic-number fractions.
This is why a legitimate Lichtenstein print does not always carry a conventional edition number such as 25/100. The expected proof structure should be verified against the specific catalogue entry.
7. Roy Lichtenstein Gemini G.E.L. Blindstamps and Workshop Marks
Gemini G.E.L. produced many important Lichtenstein editions, and its workshop markings can provide useful supporting information when identifying a print.
For example, the catalogue documents Peace Through Chemistry IV, 1970, with a Gemini blindstamp on the front and Gemini G.E.L. stamp on the reverse. Other Gemini editions may also carry workshop numbers or embossed chops.
Not every authentic Lichtenstein print has a Gemini mark. The expected printer, publisher and workshop markings depend on the individual edition.
8. Signed vs. Unsigned Roy Lichtenstein Prints
Many important Lichtenstein limited-edition prints were hand-signed, but not every legitimate printed work follows the same signature or numbering format.
Some exhibition prints and posters were issued unsigned or unnumbered. For example, the Roy Lichtenstein Foundation records Crying Girl, 1963, as not having been issued in a numbered edition; examples without mailing information were often signed by Lichtenstein and sold or given away through Leo Castelli Gallery.
Likewise, Modern Art Poster, 1967, was issued in an edition of 300 with additional unsigned, unnumbered proofs documented by the Foundation.
An unsigned or unnumbered Lichtenstein work is therefore not automatically inauthentic. The correct question is whether its signature, numbering and physical characteristics correspond with the documented edition or poster.
9. Does a Roy Lichtenstein Signature Prove Authenticity?
No. A signature is only one element used when researching a Roy Lichtenstein print.
The signature, edition or proof designation should correspond with the documented medium, paper, dimensions, printer, publisher, workshop markings and catalogue reference for that specific work.
A convincing-looking signature on a print whose physical characteristics do not match the documented edition should raise questions.

Quick Checklist for a Signed Roy Lichtenstein Print
- Signature placement
- Date
- Edition number or proof designation
- Corlett and RLCR references
- Printer or publisher
- Blindstamps and reverse markings
- Paper and dimensions
- Condition and provenance
The goal is not simply to determine whether the signature “looks right,” but whether the complete work corresponds with the documented edition.

Frequently Asked Questions About Roy Lichtenstein Signatures and Proofs
Did Roy Lichtenstein sign his prints?
Yes. Many original Roy Lichtenstein limited-edition prints were hand-signed, frequently in pencil. The signature placement and accompanying inscriptions vary by edition.
What does AP mean on a Roy Lichtenstein print?
AP means Artist’s Proof. These impressions exist outside the regular numbered edition and should correspond with the documented proof structure for the work.
What does PP mean on a Roy Lichtenstein print?
PP means Printer’s Proof. These impressions were generally reserved for the printer or workshop and may exist in very small numbers.
Are Roy Lichtenstein artist’s proofs more valuable?
Not automatically. Value depends on the individual print, rarity, condition, proof type, provenance and collector demand.
Does a lower edition number make a Lichtenstein print more valuable?
Usually not. A lower number within the same edition does not normally create additional value by itself.
Does a Roy Lichtenstein signature prove authenticity?
No. Signature, Corlett and RLCR references, edition information, medium, paper, dimensions, printer, publisher, workshop marks and provenance should all be considered together.
