The critically-acclaimed, year-long Pomona College Museum of Art exhibition, “It Happened At Pomona: Art at the Edge of Angeles, 1969-1973,” ended in May. But as this photo tweeted by KSPC’s Erica Tyron shows, interest in the exhibition carries on, far beyond Pomona. The shot shows the display window of San Francisco’s famous City Lights Bookstore, and the gray-colored tome is the catalogue for “It Happened.”
