This uncommon and dazzling hand signed Op Art silkscreen is from the famous 1965 Galerie der Spiegel portfolio. (Six Seritypien). It is perfectly square, measuring 24 1/4" x 24 1/4". This particular work was featured as an impressive full page reproduction in the "Documenta Kassel" exhibition of the Sixties, Documenta 4, and is one of the artist's most iconic series from the 1960s. Other editions of this piece are already in the permanent collections of major museums like the Museum of Modern Art and Tate Galleries, making it difficult to come by in such good condition.

It is Schoellers Hammer Karton paper. (Printer: Edition Domberger, Stuttgart, West Germany; Publisher: Galerie Der Spiegel, Koln, West Germany.) The print is hand signed but not numbered, as the Der Spiegel portfolio was numbered on the colophon.

Richard Anuszkiewicz is considered one of the founders of the Op Art movement in the United States. He began his career as a figurative artist, studying at the Cleveland Art Institute, but after winning a Pulitzer traveling fellowship to Yale University to study under Josef Albers, Anuszkiewicz' entire career changed, and he moved into colorful Op Art abstraction. He has been exhibiting for over six decades, and his work is in major museums and collections worldwide. Now in his mid-Eighties, Anuszkiewicz' is enjoying a huge resurgence in popularity. In recent times, both Christie's and Sotheby's announced they had achieved the highest prices ever for Anuszkiewicz' work at auction.
