On the 1906 Sanborn Fire Insurance map, Martha Jackson's house is at the top center, labeled 106. The code "D" stands for "Dwelling" and the color yellow indicates wood frame construction. The street across the top is E. Second Street, with Center Street running north-south on the left. The structures marked "Female Boarding" are brothels. | Creator: Sanborn Fire Insurance Company | Date: 1906 | Source: U.S. Library of CongressDownload Original File
