Yellowstone and Grand Teton National Parks guidebook. Issued by the Union Pacific system circa 1928. This 48 page guidebook has no writing with the exception of a former price and has a solid binding. I could find no tears and the interior is clean. There is light corner wear throughout. The cover has corner wear, very light browning, light creasing, corner and edge wear. I will ship this book USPS mail. Please email me with any questions.
