A 50-year retrospective of SECA exhibits is a difficult task for the San Francisco Museum of Modern Art (SFMoMA) to undertake. We are talking about 50 years of art in the Bay Area, with every movement that has happened and in every medium that has been explored as a part of it. I applaud assistant curators Alison Gass and Tanya Zimbardo for undertaking this daunting task. Fifty-year-old SECA (Society for the Encouragement of Contemporary Art) is an auxiliary group of SFMoMA.
