Dramatic horsehead sculpture in wood, mounted for wall hanging. This is larger than you might think, about 14 to 16 inches high and about a foot across the base.

Excellent  condition, just unearthed from decades of storage in a climate-controlled storage unit. No perceptible chips or scratches; notably the tongue and tips of the ears are intact. Study the photos.

I don't see that this is identified as any specific famous racehorse, so he could be your Mr. Ed.

The tongue looks to me like maybe he's trying to get that peanut butter off the roof of his mouth.
