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.
Jessie is a chestnut leopard appaloosa on the Weanling. Designed by Elena Christopher (aka Elaine Stone). The model has a customized twitched tail. Pictured with the ISH - 4WJF.
