This map of the vicinity of Breckenridge was drawn by F.C. Cramer, Mining Engineer, and issued by the passenger department of the Denver, Leadville & Gunnison Railway Company. It depicts the valuable placer mines in bright yellow primarily along the Blue and Swan rivers and also locates numerous lode mines. This region was part of the Colorado Gold Rush of the 1860s, and gold continued to be mined with success through the end of the 19th century. Accompanying the folding map is an additional full page "Map of Colorado" (7.4 x 8.0") showing the lines of the Union Pacific, Denver & Gulf as well as the Denver, Leadville & Gunnison Railroad. The 16 pages of text accompanying the maps entices both investors and prospectors to the area. Folds into tan paper wrappers (4.2 x 8.7"). No past sales records and only 1 institutional example located on OCLC (Denver Public Library).
