Rosenbaum's is typical of major downtown department stores built in towns across the country. First appearing in the 1860s, department stores offered a great range of goods and services under one very large roof, a contrast to the variety of speciality stores which had previously comprised downtown commercial areas. Their popularity grew as the goods and services offered increased, and shopping at the department store became a pastime of middle-class women. From the 1890s to the years prior to World War I department store construction boomed. Stores like Rosenbaum's were larger and more luxurious than their predecessors, and symbolized America's growing consumerism.
Rosenbaum's Department Store is located at 118 Baltimore St., and is a contributing building to the Downtown Cumberland Historic District. Now the Keystone Financial Bank, it is open to the public during normal banking hours.
