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.
New Attitude is a bay Pony designed by Sheryl Leisure. There is a Non-Custom version and a Custom version. The Custom version has a short swishing tail. All were available in matte and glossy finish. The total run of both custom and non-customs was 250.
