|Stockmen's Bank is locally significant under National Register Criterion A in the area of commerce as a place of repeated activities that facilitated commercial and agricultural development from its construction in 1919 through its unexpected closure in 1949. Originally constructed and opened as the State Bank of Martinsdale, the building is also importantly associated with banking trends in Montana as it witnessed the closure of that institution in 1923 at the height of the post World War I agricultural depression and banking crisis. However, the building also represents a counterpoint to those trends in Stockmen's Bank of Martinsdale, successor to the State Bank, which survived for twenty-six years during an equally tumultuous period that included the 1929 Stock Market Crash, the Great Depression and World War II. The bank is also significant for its dramatic closure in 1949 after it was discovered its longtime cashier had taken approximately $205,000 from the bank over several years. It represents one of the great dangers of small town banking-an institution run by a single employee with little accountability. Finally, Stockmen's Bank is also significant at the local level under National Register Criterion C as an excellent example of a one-part commercial block building, as well as Martinsdale's only brick building and its only commercial building expressing an architectural style (Neo- classical Revival).
