This photograph shows several of the stamps used in the Sherwood correspondence books. In the center of the photo is the base stamp for a two-part process. It is the body of a seated man, with some detailing and a few facial features. Above that stamp and to the right is the second step stamp, which would lay down the outlines of the man's body, facial features, and other small details.
