1929 Sanborn Insurance Map of the 12th and Broadway Area
1929 Sanborn Map showing Auto Related Businesses on the block. All the businesses along Broadway are indicated as either garage, auto sales or auto sales and service. On Lincoln only two areas are shown as domestic areas, the attached domestic homes at the corner of 12th and Lincoln and an apartment building in the center of the block.
The maps were created by the D.A. Sanborn Company, founded in New York in 1867. They are a valuable resource for research in architecture, site assessment (like the History Colorado project), genealogy and urban history.
