There was an inscription on the image. "Blair was located three miles north of Silver Peak and was founded in 1906 by the Pittsburgh Silver Peak Gold Mining Company whose 120 stamp mill (under construction in the foreground) overlooked the town. Ore from the Mary Tunnel reached the mill via a 14,000 foot aerial tramway. The town's population was 700 and Blair was served by the mining company's Silver Peak Railroad. Blair prospered until 1917 when the mine and mill were closed. The mill processed over $6,000,000 worth of gold ore.
