Two original CDVs originally side-by-side in the Callinan family album, of San Francisco and Sonora, California. They were taken in the same sitting by San Francisco studio of H.W. Vaughan. They are not identified, but based on other identified photos in the same album, I am pretty sure they were brothers Michael and William Callinan, 8th and 9th regular Army Infantry.
CDVs are 4" x 2.5" with minor soiling, wear.
