 In 1969, Wacky Packages included a mock ad, drafted by Art Spiegelman and painted by Tom Sutton, depicting a flag-waving American Revolutionary soldier and a pair of club-wielding policemen chasing a group of hippies carrying picket signs inscribed "For Freedom!" and "Love! Not War!", with a prominent slogan, "Keep America Clean with Commie Cleanser" and a can, depicting a caricature of Uncle Sam, and inscribed, "Extra Strong Commie Cleanser" and "Gets Rid of Reds, Pinkos, Hippies, Yippies & Flippies". The mock ad has also appeared depicting the can alone.
