San Francisco: Society for Individual Rights, 1971. Magazine. 48p. including covers, 8.5x11 inches, ads, illustrated with photos and a calendar of events, very good magazine in stapled pictorial wraps.
S.I.R. was an extremely important homophile organization in the 1960s-70s and "Vector" was the main gay magazine for the Bay Area during those years. The magazine began life as a newsletter in 1964, merely several folded and or stapled sheets with news and calendars. The late Sixties found the magazine concentrating more on local and national news of interest to gay men.The final years saw the magazine turn more to a standard gay men's magazine with photos of young men from around the Bay Area.
