The image of the Great White Throne on the cover of this menu is from almost exactly the same location as earlier menus in the art nouveau series. But the previous images were hand-colored versions of black-and-white photos, while this is labeled a “natural color photo.”
The back of this menu has a printer’s date of January, 1935, while the inside is dated 3-15-35, which would be the date the menu items were printed on a menu blank. I saw a menu with the same natural color photograph on ebay that was dated 1932 and which also credited the photo to Frank G. Fulton. This menu cover is shown below.
I can’t find any information about Frank G. Fulton except that Union Pacific also credited him for another photograph of Zion shown in the advertisement below.
The menu itself was used on the Los Angeles Limited, Union Pacific’s premiere train at the time, and had five “club breakfast” selections ranging from 50 cents to a dollar plus the usual a la carte side. Multiply by eighteen to get today’s dollars.
