Ah, the Law West of the Pecos, I know about him from the French comic Lucky Luke. Also about Black Bart, including the fact that he was tracked down to a mild schoolmaster, who dined at the same luncheonette as the Pinkerton or whoever detectives hired by Wells fargo to find Black Bart, hah hah, because of a laundry mark on the overcoat he wore as a disguise, and that he left poetry at with his victims (I've labored long and hard for bread, for honor and for riches, but on my corns too long you've tread, you fine-haired sons of bitches)...
