Rare vintage 3.5 x 5.5 postcard photo by noted Glacier National Park photographer T. J. Hileman, signed in the lower border in black ink with the chief’s three-character pictogram of a man, a majestic eagle and a calf. In fine condition, with some scattered light silvering to dark areas of image. In the 1920s, when access to Glacier National Park was primarily by train, a group of Blackfeet Indian “chiefs” would greet new arrivals and offer to sell photographic postcards of themselves. “Chief” Eagle Calf (John Ground) was part of this group. The postcards sold for a nominal price and could be autographed for an additional cost, which was the case with this card. RRAuction COA.
