Through June 2 - Manitoba Museum of Finds Art at Will Brown. Resuscitating a subversive slice of San Francisco history, this exhibit consists of objects from the original Manitoba Museum of Finds Art that was founded in 1974 by Alberta Mayo when she worked at SFMOMA as assistant to then-director Henry T. Hopkins. Run right out of Mayo's office, the Museum displayed quirky items that accumulated from other museum employees and artists alike and also staged events like a Bruce Conner look-a-like contest and an accompanying bake sale. Marvel at the old SFMOMA Rolodexes (enticingly flipped to Wayne Thiebaud's contact info when I was there), a kitchen hot pad printed with an atomic bomb blast, a jar of cotton balls used by a museum conservator, and much much more. The Will Brown show includes a collage of historical photographs and flyers documenting Museum events and exhibitions, and there's even a gift shop where you can pick up your own ephemera. I recommend the "sheesh" button.
