Dorothy's Dream pull chains are reminiscent of the movie "The Wizard of Oz". Yellow beading represents the yellow brick road. The swirled painted rainbows on shells is for the infamous song Dorothy sung and is still a favorite of all time, "Somewhere Over the Rainbow". The red in the rainbows are for her ruby red slippers she clicked. And last was the great and powerful Oz who was to take her home in his hot air balloon. If you love that movie this set is a must.
