Oh what was it???
There was a fantastic site I found once that had all kinds of vintage male nudes of all kinds ranging from Thomas Eakins-era up through the modern age. They were just pics of guys from a time when being nude wasn't a big deal. One set was of miners showering, some were military, others I didn't know what, but they were fantastic. Not sexual, just a kind of celebration of guys being nude together. I wish I could think of it.... anyone know?
