Here's a picture of Big Bill Broonzy with the Gibson guitar that I mentioned in my previous post - on an album cover from Yazoo Records. Yazoo always had a great selection of hokum music with wonderfully illustrated album covers by R. Crumb and Robert Armstrong (two of my favorite underground comic artists who also had a great band called Cheap Suit Serenaders).
