9 images of the Moon at different phases, from New York, March 6, 1865-May 19, 1874, albumen prints mounted on black cabinet cards with pasted-on printed captions below, images 5 x 5 inches (130 x 125 mm), printed and published by O.G. Mason of New York.

Oscar G. Mason [1830-1921] worked as a daguerreotypist, later directing the Photographic Department of Bellevue Hospital in New York City. At the same time, from 1865 onwards, he was publishing Rutherfurd's photographs of lunar phases. He seems also to have been involved in their production, for in 1887 Mason gave a detailed description of activities at Rutherfurd's observatory, writing "From his observatory we started for the moon, or, rather, under its great revolving dome found means for pulling the moon down, to be hung on the wall for our inspection" ("A Voyage to the Moon," in Scientific American Supplement, no 606, August 18, 1887, pp 9684-9685).
