One of the top categories of paper memoribilia that I collect is passenger route guides. Other than region specific guides such as those for the Ozarks and the Gulf Coast , I have only found one general route guide for the Frisco system: Friscorama. By the name trains listed on the back cover map, it appears the route guide dates from about 1938.
The style and content organization is similar to the WPA Guides from the 1930's. I wonder if there was some inspiration for "Friscorama" from the Guides.
In the niche of Frisco promotional collectibles, there were tourist brochures published about Lake Taneycomo and "Top of the Ozarks." There were also promotional booklets for the individual states extolling the economic benefits of each state in the Frisco system. Rock Island had a similar such series.
Map looks to be around mid-1939, the Current River Branch has been pulled back to Chicopee (ab.1938/1939) but the Rogers, AR.-Grove, OK. (ab.1939) & Grassy Bayou-Caruthersville, MO. (ab.1940) branches are still there
