I just came across these with this information so I'm passing it on:
Photo booth, c.1953 (Hastings Park, Edmonton, Canada):
These pictures were once owned by the young man on the right-hand side of the image, Joseph John Bertrund Belanger. Belanger, for most of his life, was a devoted collector of LGBT history. Born in Edmonton, Canada, in 1925, he served in the Royal Canadian Air Force and was a member of the Mattachine Society — an early instance of what today would be called an LGBT organization — in the early 1950s. It is thanks to his passion and foresight that the image survives today.
