In the late 1950's, the first satellites were placed into earth orbit to worldwide amazement. Duncan capitalized on that event with a the Satellite yo-yo, an odd shaped model that looked a lot like Saturn.
But this one took the odd shape to a new extreme. The halves of the Seattlite are shaped like the famous Space Needle tower in Seattle. Painted in two tone, the story is that these were sold only at the tower in Seattle. It was made exclusively for the tower during the 1964 World's Fair. Quantities unknown, but this is a very hard to find release from Duncan.
This one is almost new, with just a few chips here and there. Also, the logo on one side is weak, or I would have rated it a 9.
