Printed postcard for the Jerry McSafety Club, featuring an illustrated or printed image of the Jerry McSafety dummy character alongside a police officer figure with bold red and yellow graphic design elements and the text The Endless Freedom. The card was produced by Frank Mack of Rock Island, Illinois, in cooperation with Michigan Mutual Liability Company, the Detroit Police Department, and a bureau of safety. The reverse functions as a safety pledge card, inviting the recipient to sign a pledge to be a good citizen, respect the rights of others, and observe safety rules before stepping into the street, with the instruction that signing the card makes the recipient a member of the Jerry McSafety Club. This card is a companion piece to the Jerry McSafety Ford dealer card in this grouping and together the two cards document a coordinated ventriloquist character safety campaign of the mid-twentieth century with multiple corporate and civic sponsors. The front bears the printed text: Printed illustrated design reading Jerry McSafety Club with police officer figure and The Endless Freedom text. The reverse reads: Printed POST CARD reverse with safety pledge text, Frank Mack Rock Island Illinois, Michigan Mutual Liability Company, Detroit Police Department, Bureau of Safety.
