Esslinger's Bock Flat Top Can

Esslinger's Bock Parti-Quiz Can

This 12-ounce steel flat top can dates to the 1950s and represents a seasonal release within Esslinger’s celebrated trivia container series. Featuring bold red "BOCK" typography set against a silver metallic background covered in trivia entries—including the caption line noted for sound moving through steel—this can integrates the brewery's "Facts for Fun" and "Parti Quiz" campaign into its bock packaging. At the center sits a red oval medallion framing the company's trademark "Little Man" waiter mascot, with the slogan "Philadelphia's Premium Beer" anchoring the bottom band.

Esslinger’s introduced the Parti-Quiz concept to transform beer cans into interactive entertainment for parties and social gatherings. Each can featured an assortment of historical notes, sports milestones, scientific trivia, and geography tidbits intended to spark friendly barroom and living room games. Prominently featured on the label is the "Little Man," a uniformed bellhop and server mascot introduced by the Brown family after Prohibition. The character became one of Philadelphia's most recognizable advertising icons, appearing on tavern signs, billboards, and delivery fleets throughout the mid-Atlantic region.

George Esslinger founded the brewery in Philadelphia in 1868, eventually relocating operations to a long-lived facility at 10th and Callowhill Streets. Following the founder's death and the start of Prohibition, the business was acquired by the Brown family, who sustained operations and modernized the plant. Following the repeal of Prohibition, Esslinger's established itself as an early local pioneer in canning beer. Through the mid-twentieth century, the brewery persevered as one of Philadelphia's prominent independent brewing firms before consolidation and changing ownership led to the facility's closure in 1964.

Within the breweriana community, Esslinger's trivia-themed cans represent one of the most popular and extensively collected sets of the flat top era. The multitude of different facts, printings, and color arrangements creates an engaging pursuit for set builders, with seasonal bock examples from the series holding a particularly special place among collectors of classic mid-century cans.
