1970s San Francisco Street Artists 2.25" Pinback

1970s San Francisco Street Artists Pinback Button. A large 2.25". Research revealed: "During the 1970s some San Francisco merchants and so-called liberal politicians were quoted in the San Francisco newspapers referring to Street Artists as “parasites”,”hippie element”, “unfair competition” and insisted that they be arrested repeatedly. One Arts Commissioner upon hearing that the Arts Commission would be tasked to oversee the Street Artists stated that it was a “demeaning imposition” on the Arts Commission. Further stating: “It’s a matter of a public nuisance, not of artistic judgment.” ...It was fascinating and there are some wonderful videos recently uncovered ( and now on YouTube) that show their struggle. I have various items in the collection where the original owners had procured them from Street Vendors in San Francisco. This was worn by one such artist / vendor.
