I count 27 beautiful color photos in this booklet. While the cover illustration is intriguing, it is entirely a fantasy: no railroad comes anywhere close to getting a view of Mt. Moran in the Grand Tetons. Old Faithful was popular enough that Union Pacific felt it was worthwhile to include not one, not two, but three different photos of it, two in color (pages 5 and 19) and one in black-and-white (page 11).
With this booklet, I have now posted every Union Pacific summer tours booklet from 1930 through 1940, along with 1925, 1927, 1942, and several post-war booklets. The post-war booklets didn’t change as frequently, but I’ll keep an eye out for 1926, 1928, 1929, and 1941.
