After my grandfather retired from horse racing, he bought a some farms and traded in horses of all types, Shown is an old family photo of a horse he apparently had for sale...probably a hired hand holding the horse.
The horse is a Percheron. Not the largest or tallest, but still of good size and very much in type. Shown also, the reverse of photo.. Back then $600 would be a very healthy sum.. probably could be now estimated at 10X the $600..
