National Bohemian Bock Flat Top Can

Baltimore's National Bohemian Bock

The National Bohemian Bock Flat Top can was produced by the National Brewing Company of Baltimore, Maryland. Known affectionately to locals as "Natty Boh," the National Bohemian brand is deeply intertwined with Baltimore culture and mid-century brewing history.

While the standard pale lager served as the brewery's flagship offering, this seasonal bock was packaged specifically for spring distribution. Because bock was brewed in limited seasonal batches compared to the flagship lager, these bock cans were produced in smaller quantities and remain sought after by regional breweriana collectors.

The graphic design of the can prominently features the brewery's famous mascot, "Mr. Boh"—the iconic, one-eyed character with a handlebar mustache who came to define the National Brewing Company. Complementing Mr. Boh, the label incorporates traditional goat imagery associated with German-style bock brewing, set against the brand's classic typography and bold seasonal color scheme.

Among collectors, known variations exist across manufacturing runs. These differences typically appear in minor elements such as canning manufacturer identification marks, mandatory tax or legal statements, and lid stampings. These packaging nuances reflect the evolving production practices of the National Brewing Company during its era of regional expansion.
