REAL PHOTO POSTCARD OF HILLTOP STRUCTURES OVERLOOKING SAN GABRIEL VALLEY, ca. 1910s. The view may be from the Puente or San Jose hills looking north, and there are roofs of possibly four structures in the foreground, farmland in the valley below, and the San Gabriel Mountains in the distance. At the bottom is an ink inscription, "San Gabriel Valley, California." On the reverse is a message that makes some reference to the image. The postcard was not stamped, so it may have been mailed in an envelope. The condition is good.
