Mystery Horse is a secret, for now. He was commissioned as a gift for his owners, and thus I cannot reveal him until it won't ruin the surprise. I am, if you'll forgive the metaphor, chomping at the bit: he's gorgeous. And adorable. Which, given his size, "adorable" shouldn't be an option, but he is.
I will update with a new post when I am given the all-clear from the buyer.
