late 60s nude duo by J. Brian

Once it became legal to publish a completely nude male figure (c. 1966-1968) and the posing straps fell away, the need to couch erotic male images in coy costumes and poses gave way to blatant, in your face exhibitionism. Still, for all that, there was a "cross-over" period where the studios/photographers still tried to get good-looking guys and pose them in pleasing ways before they realized that any pic with a hard-on would do to make a buck.

The man known as "J. Brian" (I have a bio of him somewhere, written by a friend of his -- I'll try to find it one of these days) came into his own during this cross-over phase, and some of his nudes are quite wonderful. He stayed in the male erotica business into the 70s and, I believe, the early 80s, publishing magazines and even producing films.

These two make a nice couple...
