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! If you're a manufacturer, or just a big collector and you want to help support the Museum drop me at line at chimera@yoyomuseum.com Keen Eye Spinabolo Tournament Model Exhibit #416 Type Production Shape Concave )-( Axle Fixed Size 6.5" Dia by 6" Wide Weight 169 g Estimated Value $10 Condition 5 Date 1960 Owner David Hall Compare Keen Eye made two versions of their Spinabolo, the Tournament Model and Playground Model. Pictured here is the Tournament. The only difference was the size. The Tournament is the larger version, and also has holes in the halves near the axle. These are simple molded plastic halves, which warped easily with heat. The halves also have molded writing.
