This densely illustrated pictorial map is color-coded to show airline routes in the United States and extending to portions of Canada, Mexico, the Bahamas and Cuba. American Airlines routes are depicted by thick red lines, while other routes are noted by a thin green line. Filling the map are numerous vignettes displaying points of interest, leisure activities, historical sites, and more. The verso contains twelve strip maps showing airline routes between various cities and a section of descriptive text entitled "The Radio Beam is the Highway of the Air." The use of radio signals for commercial aviation increased exponentially following the military's enhancements of this technology during World War II.
