This photo looks like it used to be the front of a postcard; the size is right and judging from the light water stains and peeling layer, the back portion has fallen to the wayside. Photo features the Rocking Stone and Rocking Stone Restaurant located in the New York Zoological Park. There is a copyright date of 1905.
Found in "The Scarlet Letter" by Nathaniel Hawthorne. Published by Houghton, Mifflin and Co., 1878.
