(CO. - Postal) Post Route Map Colorado, U.S. Govt., Nov. 1951 A map for an essential layer of infrastructure at the time, even as telephony begins to dominate the culture. Postal maps show the physical routes used to connect towns to mail distribution, but it also identifies what was truly established as far as small towns across the state. While it shows towns, counties, drainages and railroads, it's really about those lines that show how the mail moved, even to the smallest towns in the mountains and remote plains. This large reference includes some manuscript notations. Condition is good with some scuffing and loss to the top border, but not effecting the map content. Rare. Image size is approximately 34.5 x 50 (inches)
