This poster is one of a small handful produced to promote that historic 1971 Tate exhibition. Warhol has boldly autographed this example, which remains in pristine, mint condition, entirely free of flaws. His signature spans a striking 7½ inches across the lower white portion of the poster, providing a perfect visual contrast. The poster itself measures 19¾ x 29¾ inches.

The image of Marilyn featured here is one of the most recognizable and culturally enduring portraits in modern art. Warhol’s depiction—vivid, evocative, color-rich, and endlessly reproduced—has played a defining role in shaping Marilyn Monroe’s lasting public image and stands as a cornerstone of the Pop Art aesthetic. It is nothing short of an icon of American visual culture, and this signed exhibition poster stands as a rare and extraordinary relic from the moment when that image first shook the art world.
