San Francisco: The 15 Association, Inc., 1993-1996. Nine standard envelopes with the Association's return address printed and member's address labels, roughly opened which contain between 2 and 4 letters, handbills advertising events illustrated with b&w drawings of leathermen and bondage fetishists (an early on by LES) folded but in very good shape. One from 1993, 3 from 1994, 3 from 1995 and 2 from 1996.
The Association formed in SF in 1980 as a gay men BSDM club. The name comes from the bylaws which say that up to 15 men, called 'Fraternal’ members, can be voting members, while the other members are called ‘Associate’ members.
