Directly from the artist, me! I only have 2 of these left in my personal collection. The box has only been opened once for me to sign it. 

Signed in white paint on the bottom and the box is signed too. Box has ding on bottom back corner.

TRAIL of PAINTED PONIES Spooked 1E/15 RARE Signed by Artist Halloween Horse new in box. Glows in the dark!

 Inspired by the artist's favorite holiday, Spooked features a hauntingly delightful mix of classic Halloween characters. An eerie ghost emerges from a jack o' lantern on the base with more ghosts floating up through the Pony's legs. The spots on the Appaloosa's blanket have changed into a witch, black cat and bats. Spooked celebrates a childhood love for trick-or-treating, carving pumpkins, scary stories and Halloween fun.
