Hi! Been a big fan of your dad's books for over thirty years or so.
I collect paperback covers and orig. paperback artwork. My question is if there is a list of sorts of who the many artists were that painted the covers for the paperbacks. I'm specifically interested in the artwork of Carl Hantman. Two examples of Hantman covers are the older version of Mustang Man (cowboy w/ rifle slung across the back of his shoulders) and the newer version of Silver Canyon (rider chasing a horse down a canyon; this is a nice wrap around cover). As you can see, his painting style changed somewhat from the 60's to the 80's. I suspect Matagorda, The Californios and High Lonesome maybe his as well but don't know for sure.
Also know Frank McCarthy painted a number of the covers as well. Any help would be greatly appreciated. Thks! Eric
