Moses had placed this image in a box that he had labeled "Airport Mutual Aircraft Mr. Erlin 1928." Three men are standing in front of the plane. It appears as if it is the same plane that was featured in previous images. The airplane is a monoplane and has the name "Mutual Aircraft Corporation" written on the body of the plane. In addition on the tail of the aircraft the number C3746 and the name Ryan B1 plus made by "S.F. Mahoney Aircraft Corporation, San Francisco, California" is inscribed.
