Tallix Foundry is a premier art foundry located in Beacon, New York, that specializes in the creation of large-scale sculpture, casting, and fabrication. The foundry was founded in 1972 by Anthony Panciarello, who was joined by Dick Polich in 1974. Polich had previously worked at the Johnson Atelier, another well-known art foundry, where he had gained a reputation for his expertise in the casting of large-scale works. Tallix Foundry quickly established itself as a leader in the field, producing work for artists such as Jasper Johns, Jeff Koons, and Roy Lichtenstein.

Roy Lichtenstein was one of the artists who had a longstanding relationship with Tallix Foundry. He began working with the foundry in the late 1980s, and the collaboration continued until his death in 1997. During this time, Tallix Foundry produced a number of Lichtenstein's most notable sculptures, including "Brushstrokes in Flight" and "House I".

"Brushstrokes in Flight" is a massive sculpture that stands over 30 feet tall and weighs more than 15,000 pounds. It was created in 1996, just a year before Lichtenstein's death, and is one of the largest and most complex sculptures he ever produced. The sculpture is made up of a series of brightly colored steel brushstrokes, which seem to be suspended in mid-air. The illusion of weightlessness is achieved through the use of a complex internal support structure, which was designed and fabricated by Tallix Foundry. "Brushstrokes in Flight" is considered to be one of the defining works of Lichtenstein's late period and is widely regarded as one of the most important sculptures of the 20th century.

"House I" is another notable sculpture that was produced by Lichtenstein in collaboration with Tallix Foundry. It was created in 1996 and is a large-scale replica of a traditional American house. The sculpture is made up of a series of brightly colored steel panels, which have been cut and shaped to create the distinctive form of the house. The panels are held together by a series of bolts and other fasteners, which were carefully concealed to create the illusion of a seamless whole. "House I" is often seen as a commentary on the American dream of home ownership and the idealized vision of suburban life that it represents.

In addition to these two works, Tallix Foundry also produced a number of smaller sculptures and editions for Lichtenstein during their collaboration. These included works such as "Still Life with Crystal Bowl" and "Modern Head", both of which are notable for their use of Lichtenstein's signature comic book style.

Tallix Foundry's work with Lichtenstein helped to establish the foundry's reputation as one of the leading art fabricators in the world. The complex and demanding nature of Lichtenstein's sculptures required a high level of expertise and technical skill, which Tallix Foundry was able to provide. The collaboration between Lichtenstein and Tallix Foundry also highlights the importance of the relationship between artist and fabricator in the creation of large-scale sculpture. Without the technical expertise and creativity of the foundry, Lichtenstein's ambitious sculptural projects would not have been possible.

In conclusion, Tallix Foundry is an art foundry located in Beacon, New York, that has worked with some of the most renowned artists of the 20th and 21st centuries. Their collaboration with Roy Lichtenstein produced some of his most notable sculptures, including "Brushstrokes in Flight" and "House I". The demanding nature of Lichtenstein's sculptures required a high level of technical skill and creativity, which Tallix Foundry was able to produce.
