George Maciunas (designer) - 'This Is Not Here' (Poster for the Yoko Ono & John Lennon exhibition at Everson Museum of Art), offset lithograph, with blindstamp, published 1971, 46cm x 61cm, within an ebonized frame. Note: the Everson exhibition was a major Fluxus related event and a semi-retrospective of Yoko's career. It drew wide coverage and was filmed and televised; six thousand people flocked to the museum on opening day alone (mostly due to rumours of a Beatles reunion, although only John and Ringo were in attendance).
