As the bottom fell out of the Superhero market in the late 40s Quality dropped that content from Crack Comics and changed the title to Crack Western Comics.
Arizona Raines rains replaced Captain Triumph as the lead character.
Arizona was a clear eyed (if you could see them though the squint) strong jawed, fast gunned Westerner who rode the west with his sidekick, a young boy known only as Spurs, righting wrongs and punishing bad guys.
Of note is the fact that for the first three issues that the character appeared they misspelled his name as Ames on the cover while he was Raines on the inside.
