Duncan Yo-Yo Winner patch from around the mid to late 1950s. In this case, the yo-yo contest was sponsored by Dad's Old Fashioned Root Beer. Other soda pop brands, such as 7-Up, Pepsi, Coca-Cola, and Dr. Pepper were sponsors of Duncan yo-yo contests in the 50s. This was at a time when pop came in a glass bottle and cost either 5 cents or 10 cents.
The upper-portion of this patch has embroidered script lettering on yellow felt.
