I am Weegee’s biographer (book will be out in March 2018, from Henry Holt), and Robert is correct. Most of Weegee’s infrared theater photos were shot in the 1940s, but there’s another batch from 1953, made on assignment for a small men’s magazine called Brief. That year was the peak of the 3-D film craze, and the ones with the cardboard glasses are from that set. Getty/ICP captions don’t note this, but it gets a glancing mention in Weegee’s autobiography.

Notably, that second set of pictures was set up. Weegee hired two young people to sit in the theater and make out, because he had a short deadline to meet.
