The World of Color was a very unusual item from the old Duncan company, and one of my personal favorites. The halves were poured and molded, so the mix of glitter and foil stars could be mixed into the translucent plastic. The effect was dazzling, and many colors were produced. The side logos were different on each side, and the clear plastic caps were printed in reverse on the inside to protect the logos from wear. The caps are concave inwards, giving the yo-yo a totally unique feel.
The dazzle of the WOC made is a good advertising model for Disney's television show, "Disney's Wonderful World of Color". But this was a production model as well, sold directly from Duncan's catalog to all stores.
Pictured here is a dark red WOC with rainbow stars and glitter molded into the plastic. This one was a much loved toy, as their is some wear from play.
