Walker Evans Polaroids
Photography of Walker Evans Polaroid Collection (716 objects) for the Yale University Art Gallery.
Just showing fronts here, but project included obverse and recto (front and back) for all objects.
While some of the fronts had writing many backs had Walker Evans notes or his copyright stamp.

An indepth descripton of the project is on Page 2.
See some behind the scenes at the Polaroids blog post.
