Perhaps the most uncommon map of the territory, while being the most significant. Based off the extremely scarce, and important map by Ebert, it is a scaled down version of Ebert's work, with Blackmore's additions of hand color to illustrate the promise of the San Luis valley. A key map for the evolution of Colorado mapping, but attainable.
Good condition. Some supportive repairs. Image size is 19 x 26.25 (inches), some hand color.
