Other important events at the Gallery included the first Franz Kline retrospective in 1962, curated by Alice Denney, and the "Popular Image Show" in 1963, which included artists like Robert Rauschenberg, Jasper Johns, Tom Wesselmann, George Brecht, Claes Oldenburg, Jim Dine and James Rosenquist.

The Gallery organized the raucous "Pop Festival" the same year, which was the first occasion on which Rauschenberg performed his now famous "Pelican."

John Cage and the Judson Dancers performed, Oldenburg staged a happening called "Stars," and Robert Rosenblum delivered a lecture on Pop Art.

Among its directors were Gerald Nordland (who gave the Washington Color School its name), Charles Millard, Adelyn Breeskin and, for a short stint near the Gallery's end, Walter Hopps.

Though a New York Times article cites Eleanor "Lalli" Lloyd as the Gallery's founder,[3] she was instead an important member of the first board.
