Store poster advertisement for Genuine Duncan YoYo's. One of the largest Duncan posters I have ever come across. It measures a whopping 914mm (91.4cm or 36") in diameter.
While the precise age of the poster is unknown, I estimate that it is likely from about 1958 to 1965. The poster was found inside what was left of a small department store building located in the mid-west. The building was eventually demolished.
