This is the ORIGINAL (not a later reprint) 1984 invitation to the famous 1984 Champions show at the The Contemporary Art Center of Cleveland, Ohio. The artist who participated in this show and are named on the print are:
Keith Haring, James Brown, Ronnie Cutrone, Brett De Palma, Future 2000, Kenny Scharf, and Dan Friedman.
However, exceptionally, this poster was boldly hand signed and dated '88 in black marker by Keith Haring underneath his printed signature and date.
The original print itself is a collectors' item. When hand signed by Haring it is extremely scarce and desirable.
