Maude (in the middle) and Emma (to Maude's right) were teachers. The father and one of the sons were photographers. Original photo is 16 by 20 inches. Some of the features (eyes and hair) were drawn in with pen.
You found another one! I heard today on the radio that May was the "Great American Photoscanning Month." See: www.photopreservation.org.
Your ancestors would be proud.
