Hamm's Beer Flat Top Can

Hamm's Aluminum Top Flat Top

This 12-ounce flat top can represents an important transitional era in beverage packaging during the early 1960s. Printed along the upper rim is the promotional statement "NEW! easy to open aluminum top," signaling the canning industry's shift toward lightweight aluminum soft-top lids that made piercing the lid far easier with a standard opener before self-opening pull tabs became universal. The face of the can prominently features the brand's stylized crown of pine trees, while the lower rim bears the slogan "Refreshing as the land of sky blue waters," an advertising tagline specifically adapted for distribution from packaging facilities outside of Minnesota.

The Hamm's brand originated in the upper Midwest and became one of the most widely recognized American lager labels of the twentieth century. During the 1950s and 1960s, Hamm's surged in popularity through highly successful advertising campaigns featuring the animated Hamm's Bear mascot and catchy nature-themed jingles celebrating pristine wilderness waters. The phrasing on packaging evolved to maintain the Northwoods brand identity even when the beer was brewed at satellite locations. Although ownership transitioned through multiple brewing conglomerates over subsequent decades, including Olympia, Pabst, and ultimately Molson Coors, the brand has maintained a lasting cultural presence.

German immigrant Theodore Hamm founded the parent brewery in Saint Paul, Minnesota, in 1865. After surviving Prohibition through diversified products, the brewery experienced massive postwar growth and sought a nationwide footprint. To supply the East Coast market, Hamm's acquired the historic Gunther Brewing Company plant in Baltimore, Maryland, around 1959. Production under the Theo. Hamm name in Baltimore was relatively brief, as the facility was sold to the F. & M. Schaefer Brewing Company in 1963.

Within breweriana collecting, this can is especially prized for its association with the short-lived Baltimore operation and its demonstration of can manufacturing technology in transition. City mandatory variations of iconic national brands remain a popular focus for enthusiasts of regional brewing history and mid-century advertising.
