REH: Two-Gun Raconteur was kind enough to let me guest post on their site.
The article is titled The Kid, Two-Gun, and History. It's about the influence of Billy the Kid, more specifically Walter Noble Burns' book The Saga of Billy the Kid, on Robert E. Howard, his writing, and the the direction he took toward western lore and stories the last few years of his life. When you get a moment go check out the article.
Also, this site is one of the best Robert E. Howard sites on the internet, so if you have several hours to spend, the site is well worth the time invested. I've spent many hours reading the site's archives. And I can assure you that was time well spent. Cheers!
