Looks like it has been on wall a while with some deterioration due to weathering. New York based Swoon has come to San Francisco over the years with her visits punctuated by art suddenly appearing on the streets of the Bay Area. There are several still up. One is in the Mission off 24th St a block on Hampshire. She had a show with Monica Canilao @__moreferalthan__ (whose art we showed yesterday on The Stud) in February 2016 at Chandran Gallery that was widely attended. This could have been pasted up at that time. . This is her father who died a year prior to the opening of the Chandron Gallery show. She shows a bit of the process of creating this paste up on her page. . Learn more about Swoon on Instagram at @swoonhq .
