KAYO MUSICAL YO-YO - 1930'S tin yo-yo from the company that also manufactured Duncan's tin yoyo's. Last 2 pics show a small indention spot, could be from manufacturing seeing as how the paint is not cracked or otherwise messed up due to it. Bright lithograph Captain's Wheel pattern. Displays nicely and it has a strange whistling sound when thrown, I wouldn't call music but that's me. Excellent condition for a 90yr old yo-yo.
