KID COLT was a character that pre-dated Kirby at Marvel, and was the main western character who he didn't redesign. He did draw a lot of covers for the series, including this early gem inked by Dick Ayers.
I really like the composition of this one, with the multiple levels, almost a 3-D effect. The faces of the horses are great as well. Also kudos to the anonymous Marvel production types of the era for a lot of little touches in the colouring, and the way that horse's leg comes in front of the title card (on the other hand, that giant CCA stamp covering part of the logo is an eyesore).
