Great tune! The rider on the horse is wearing glasses...and is obviously intended to recall Teddy Roosevelt and his Rough Riders. Teddy's horse was named "Little Texas".
I magnified the artwork as large as it would go and I still don't see the glasses. Maybe *I* need glasses. But the horse! The horse strongly resembles the horse in the photo. I think "Little Texas" would be a great title for a Banjo Solo.
