NO MEN'S EARRINGS AT TIFFANY:
Reading through a 1965 edition of Tiger, a magazine that consisted of text reprinted from seminal gay rag Drum and pictures from the Minnesota-based studio, DSI Inc, I came across a Tiffany & Co ad reading "We're sorry. But we do NOT carry earrings for men. Nor will we." As seen here, the magazine explains the advert appeared in the New York Times on December 6, 1964.
I recall once hearing something about Tiffany creating the policy to thwart homosexuality, but couldn't quite place the memory. I did an online search on the matter and came up with a similarly hazy comment left on a 2009 NYT article about Tiffany selling men's earrings. Wrote the reader, "I seem to remember a Tiffany’s sign in the store on Fifth Avenue, in the 70s. A small card on which was printed: “Tiffany & Co does not sell men's earrings, and they never will.'" Clearly Tiffany has changed their policy, but does anyone else remember this being a thing?
