The Zombie Cowboy was a Spirit exclusive static prop that was sold during the 2007 Halloween season. The company that made him is not clear, however, it seems to be the case that YJ Toys and Crafts created him since he uses the same face mold as the Bone Collector, which is another YJ Toys and Crafts prop. The Zombie Cowboy did have a page on the 2007 version of Spirit Halloween's website, according to the Wayback Machine archive but the stock image is not present. And when you click on the link it'll take you to Spirit's 2013 website. Not a lot of information is available for him as very little people own him, making him one of the rarest Spirit Halloween items.
