The Artisan Hall Series is a program where artists would visit the company and hand paint an entire run of models. The artist would sign and number each model. The early releases came with a paper Certificate of Authenticity signed and dated by Peter Stone. Later, each model came with a Collector Card with the model's description and a pre-printed signature by Peter Stone. Each run was limited to 200 pieces.
The 15th release was a glossy red silver paint ISH called Goo. Painted by Sarah Minkiewicz-Breunig. Some models are missing the hand drawn heart on the right side, and an unknown amount of mares were made.
