- Seattle, 1933
- Detroit, 1941 (in reference to this news article claiming Detroit's about to get its first ever "significant transit line")
- Minneapolis, 1946
The implicit argument is that significant investment in public transit is not at all novel or un-American, but I find the maps interesting even aside from the politics of mass transit.
Just for giggles, I looked up a couple of others:
Grand Rapids, MI, 1927 (this is a proposed streetcar expansion map, but it is clear that in 1929 GR had a significant and widely used streetcar system)
Washington, DC, 1888
Dallas, TX, 1905
