Alan Selby (1929–2004), born Alan Henry Sniders,[1] was an English-born American gay businessman and leader in the San Francisco leather community.[2] He was known by many as "the Mayor of Folsom Street".[1] He claimed to have created the first hanky code with his business partners at Leather 'n' Things in 1972, when their bandana supplier inadvertently doubled their order and the expanded code would help them sell the extra colors they had received.[3] However, other sources dispute this being the origin of the hanky code.[4]
In San Francisco, the signs began appearing around 1971. The Trading Post, a department store specializing in erotic merchandise, began promoting handkerchiefs in the store and printing cards with their meanings. The red and blue handkerchiefs and their significance were already in existence, and meanings were assigned to other colors as well.
