A city with more headlines about the tech industry than the art scene, San Francisco once had three spring time art fairs: Art Market (formerly, artMRKT), Art Pad and SF Fine Art Fair. Last year it narrowed down two. This year, there was only one art fair left standing: Art Market San Francisco, which ran May 15 through May 18. The closure of the other two fairs did not seem to be a bad omen for Art Market, however, which featured a diverse assortment of national galleries that offered many different flavors of contemporary, from Pop-inspired to dark to abstract. San Francisco art fairs tend to be home-grown productions, with Bay Area galleries dominating the landscape, but this year’s Art Market welcomed many exhibitors from other cities.
