New York: Yippy, 1971. First Edition. Rather early poster commission by the artist and art-world provocateur Robert Cenedella. Cenedella is perhaps best known for his 2018 lawsuit against five American art museums, in which he alleges that museums and private gallerists have been co-conspirators in denying certain artists -- including himself -- mainstream success. The current design, delightfully unironic, reproduces the insignia of the United Nations in day-glo colors, with psychedelic typography at lower 1/3 of image. Apparently uncommon; we find no catalogued examples in OCLC; not in the on-line catalog of the OAC. Original machine lithographed poster in colors, 72cm x 58cm (ca 28-1/2" x 22-1/2"). A few minor edge-creases, but a bright, unfaded, unworn example, Near Fine (A-). Unbacked.
