To quote from Lucky's Collectors Guide to 20th Century Yo-Yos, "All Duncan yo-yos marked ‘Tournament Yo-Yo’ are classic tournament shaped. When adults reminisce about their childhood yo-yoing days, this is the yo-yo most commonly described. Duncan produced millions of Tournament yo-yos. Over the de­cades, several different seals bore the word ‘Tournament’ and most carried the familiar decorative airbrushed paint stripe on both faces."
