1967 This image was designed for the Pasadena Art Museum's 1967 Lichtenstein exhibition and was also produced as a poster. Auction records for this print indicate the possibility that an unknown number of signed-only proofs may exist, but no documentation was found to verify that such impressions were (or were not) part of the edition. It is also possible that autographed posters have been mistaken as proofs from this edition.
