Kicking blue donkey between blue text encircled by blue outline over white background.
The image of a donkey coupled with the written words implies the phrase, “Stop Your Ass Kicking.” Nathan Shure’s toy company, Cosmo Manufacturing Company, was founded in 1892 and was known for creating the trinkets found in Cracker Jack Boxes. In 1926, Cosmo Manufacturing Company bought the Dowst Brothers Company, which was famous for its tiny works created using metal (including buttons, cufflinks, and other metal accessories that were intended for promotional purposes). When Cosmo Manufacturing Company absorbed the Dowst Brothers Company, the name for the new combined business was Dowst Manufacturing Company. Although the Dowst Brothers Company was known for their metal items, any buttons that are labeled "Cosmo Manufacturing" were presumably made prior to 1926 when the companies merged and the name changed. In 1937, the repackaged board game “Monopoly” (which had first been released two years prior) included new metal tokens made by Dowst Manufacturing Company. Those token designs are still used in the classic edition of Monopoly today.
