A shield-shaped Pepsi-Cola Winner cloth patch for a Duncan Yo-Yo contest, with Pepsi as the sponsor. The stylized Pepsi-Cola logo puts the date from 1950s - early 1960s. Red, white, and blue embroidery on cotton twill with a stabilizing gauze/scrim backing on the reverse.
During the postwar yo-yo booms, Duncan partnered with major retailers and bottlers on neighborhood contests. Pepsi tie-ins were common: demonstrators ran store-front or schoolyard events, and winners received patches, ribbons, and buttons. This patch likely marks a local contest win under that joint promotion.
