The origin of the portraits here are 6x7 medium format slides that I discovered at a place called UrbanOre in Berkeley California. They are the work of an unknown professional photographer in the East Bay. His portrait sitters as well are unknown to me. I assume that these were taken in the 70s but, again, I don't know - nothing on the slides revealed anything about their origin. I scanned and carefully restored these images because I think they're an interesting glimpse into the style of portraiture that was obviously popular at the time (those double exposures!).
