look at this listing from the last REA auction which mentions Walter J. Danahy, same as your photo:

"A number of player names are written on the reverse of the mount (7 x 5.125 inches) in pencil, as is the notation "Donated by Walter J. Danahy - Framingham Mass - 1951." (The name "Walter J. Danahy" sounds very familiar to us but we have so far been unable to place it.) "
