This a genius comic ad. It tricks kids into selling Cloverine Salve by thinking they are winning a contest for some foreign coins (that I am sure are worth about 5 cents). Now that you got your foreign coins, you just need to go door to door selling their fine smelling salve. What a bargain. Can you name all the countries?
Note: Cloverine, which contains White Petrolatum, Fragrance, Rectified Turpentine Oil and White Wax is still sold today in a very retro looking package.
