Sanborn Fire insurance maps documented urban growth and development in support of the fire insurance industry, which used the maps to track their risk exposure. A great source for urban historians, the maps show how American cities changed over time, revealing the contours of the city. The 1947 Sanborn Map of Phoenix shows the grocery store in pink, alongside the Mr. Yaun's dwelling (in blue), the apartments on the lot, as well as the nearby lots in the neighborhood, one of Phoenix's oldest sections. | Creator: Sanborn Map Company | Date: 1947 | Source: Sanborn Fire Insurance Map from Phoenix, Maricopa County, Arizona, 1916 - Oct. 1946, reprinted 1947, Page 43, Image 45, retrieved from the Library of Congress, https://www.loc.gov/item/sanborn00169_007/.
