Above: a very nice cover painted by Harry Schaare for Zane Grey's western The Last of the Plainsmen, originally published in 1908, with this Pennant edition coming in 1953. The book tells the story of real life frontiersman Buffalo Jones, aka Charles Jones, and a 1907 journey he made with Grey, so we can assume these two characters in the art are them, one of those rare times an author appeared in his own cover art. The story is actually set in Arizona, not Montana, just in case you took our subhead literally, which you never should. We were going to go with the best guide in Arizona ending up in Sinaloa, but we flipped a buffalo nickel and Canada won.
