A hand-written inscription on back says, "Dear Clyde, I wish you a My Xmas and a happy and prosperous New Year. D.H. Jackson." The photograph is of David Howell Jackson in La Jolla, California in 1924.
During the Rhyolite trip, a member of the Jackson party took a picture of the tent town of Bullfrog in early 1905. The Jacksons came down from Tonopah to examine a mine in Bullfrog.
