This is the first of a series of six menus from a California tour offered by Chicago radio station WLS. Though the menus are undated, other information suggests the tour left Chicago via the Alton on January 30 and returned, again on the Alton, on February 14, 1938 (the menu is for February 13, but that would have been the night before arrival). That means the tour probably went via Southern Pacific from New Orleans to Los Angeles.
Though the menu mentions only Lake Tahoe, the photo actually shows three lakes. In the foreground is one of the two Angora Lakes. In the middleground is Fallen Leaf Lake. Tahoe itself is the grey expanse in the upper third of the photo.
