Here’s a menu cover with a beautiful photo of two riders in front of what is probably Bear Lake in Rocky Mountain National Park. Unfortunately, the menu is blank, but I’ve seen other menus with this cover dated 1946, so this would have been printed around that year.
Even the back of this menu blank is blank, which is surprising because the railroads usually paired the backs with the fronts. In the other menu I’ve seen with this cover, the back encouraged people to “Come Up to Colorado” and included a schedule for the Denver Zephyr from Chicago to Denver. Perhaps they left the back blank until the menu was used in case the schedule changed.
