These days San Francisco has gay pride coming out the proverbial wazoo, but in the distant (and not-so-distant) past, the majority of gay individuals and couples had to stay painfully deep in the closet. While looking at a decades-old image capturing a free, joyous moment between a gay couple just being themselves shouldn't be such a rarity, man, it really does bring on the smiles. Artist and filmmaker Sébastien Lifshitz put together a unique collection of photographs depicting playful gay couples, as well as cross-dressers and expressions of gender fluidity from between 1900 to 1960 that he hunted down from flea markets and garage sales. Here is a selection of some of the photos from his book, The Invisibles: Vintage Portraits of Love and Pride, published by Rizzoli (available here).
