A Few Further Notes…

It may sometimes be difficult to ensure exact specificity of information for older prints where there may not be complete extant records. In cases such as these, approximate date ranges are appropriate and all editions that are known to the dealer should be disclosed to the best of their ability.

Proper terminology should be used in describing the medium of the print, the edition and any annotations that may be present. You can find more information about fine art multiple terminology by reading our articles about printmaking techniques and print annotations.
