The Signature Series was a program where an artist would design a model, and then the Stone Co employees painted them. Each model had a stylized sticker of the artists' signature, and came with a Certificate of Ownership.
Cherokee is a chestnut appaloosa pony with a custom mane. Designed by Julie Keim, and probably all painted by Julie since she worked at the factory. There were originally 250 to be made, but only 15 were sold and produced.
