George L. Beam took this sometime between 1922 and 1935.
I don't think this photo was in the Western History Collection database until recently. If the link below doesn't work, just go to [gowest.coalliance.org] and search for "Molas".
It is on an 8x10" negative and you can order prints. Or you could reverse, enlarge, color and print this digital image on some paper or transparency for a new drumhead if they let you.
