I love this photo set of Persona Diptych’s on flickr. A diptych is any object with two flat plates attached at a hinge. In the ancient world these were usually tablets that were coated with wax on inner faces, for recording notes. The term is also used figuratively for a thematically-linked sequence of two books.
Using an excellent vocab word Jason Travis does portraits of people with their stuff. Good photos, interesting subjects, and fascinating piles of crap people carry around with them.
