from the history files of car dealership competition wars, the world's largest free standing sign, 7 stories tall

The sign cost $100,000, weighed 12 tons, and was briefly North America’s largest free-standing sign, powered by a transformer that could light up 30 houses.

The BowMac car dealership had a history of staging stunts to lure customers away from the Dueck Chevrolet Oldsmobile dealership down the road. Under Jimmy Pattison’s management, promotions included dressing up a performing monkey in overalls and hiring the Leavy brothers—seven-foot-tall twins—to hang out in the used car lot. In 1958, Pattison staged what was billed as the “world’s largest checker game” where models in red or black bathing suits became the checkers moving across a board of two-foot squares.
