This two-story commercial block structure was built in 1924 by the Martindale Motor Corporation as a new hupmobile automobile sales and dealership building. The second floor contained offices for the Martindale Telephone Company, living quarters for switchboard operators, public offices, a club room and the Masonic Lodge No. 1206. A post office operated in the northwest corner of the first floor from 1937 to 1975. The motor company lost profitability due in part to the Great Depression and closed in 1938. The building was later used as a Humble Oil gas station and apartments. The architecture is an example of a two-story load-bearing masonry structure with modest details and finishes.
