The Rainbo from Duncan was a unique tin yo-yo which started production in 1934. The yo-yo has a tin body, inner and outer tin shells and a metal axle. The outer shell has "windows" displaying a multi-colored inner wheel, which spins freely. After the yo-yo has been thrown and caught, the inner wheel continues spinning, giving a rainbow effect.
