(CO.) State Of Colorado, G.L.O. - US Govt., c. 1935 An uncommon black and white map of the state from a long series of maps that would definitively document the state. But this map from the 1930's captures a stark time for the state as it struggled under the Great Depression and then the harsh years of the Dust Bowl which plagued the plains and at times reached into the front range mountains. This map depicts the draingage, railroads, counties and towns, without depicting the complex terrain. A great reference for the period. Condition is very good, ex-libris with marginal old stamp. Image size is 14.5 x 17 (inches)
