Sponsors and Curators The Museum of Yo-Yo History is a labor of love, and we would not be able to stay up-to-date with exhibits without the support of our sponsors and curators. Big thanks go to One Drop Design and Duncan for supplying us with their latest models, YoYoExpert for their help and support, and to Cody Orr, TotalArtist and YoYoBrothers™ for allowing us to use their collections!

A Dell yo-yo from the early to mid 1960s. The packaging uses the word "yo-yo" on it, but the yo-yo itself does not. In the mid 1960s, this seemingly insignificant detail--among other things--played an important part in Dell eventually ceasing yo-yo production altogether to avoid legal action taken by Duncan over the use of their trademark "yo-yo". Originally retailed for $1.00; uses a metal axle with a starburst response. This model was made out of tenite plastic and used a metal axle. Compare with the Dell Super Star-No. 604. Why this Butterfly model and the Dell "Super Star" model--also a butterfly-shaped yo-yo--use the same style number on their respective packaging is unknown. One theory is that the name "Butterfly" originally came from Duncan Yo-Yos and was considered a trademark; Dell may have decided to drop the name "Butterfly" from their packaging and yo-yo and instead use "Super Star" to avoid litigation from Duncan. Compare also with the Dell Flying Star-No. 603P, also a butterfly. Other Views Profile Close-up Package front, large Package back 2005-2023 Software © David W.
