My mother has the same picture you are questioning about. The only difference is on the front at the bottom the word "Kaloma" and the copyright are punched (imprinted, stamped) in the photograph. The back has an ink stamp- "Pastime Novelty Co." with a faded date and location. In my research a picture of the same was actioned off at about $3,000, artist unknown. I also read that Caloma was the place that J.Earp eventualy spent the rest of her life. Does your picture have "Kaloma" on it, and is it indented in the picture? I too am wondering the authenticity of my mother's picture and its history. If you have any more info. please let me know.
