Man, I've been flipping through his galleries ALL day and I haven't even seen half his stuff. This is great.
EDIT: One of the best parts of the site is the comments. It seems no matter where he is, or what he's photographed, someone knows precisely what the object is. For example, in one gallery, he was in a room full of iron lungs used for polio patients. It turns out one commenter was actually IN THAT ROOM in the hospital and shared some of his pics from his hospital stay. In another, he had a shot of a vaguely exploitative-looking "healthy foods" magazine for urban youths from the 70s. The freaking guy who created the damn thing posted there. Of course, some could be BS, but the level of detail put into their responses makes me think they're legit.
