Patent consists of a method of preparing photographs for coloring: first immersing the photo in a "clearing solution of rosin and parrafine, each previously dissolved in turpentine, and then applying to the face a coat of rosin dissolved in alcohol, and to the back a coat of the clearing solution..." Common oil colors are then applied to the back "in the usual way."
