The Pioneers of Country Music with R. Crumb and Yazoo Records

Well, I think you've only had a quarter of the fun.  His book (as distinct from trading cards) is Heros of Blues, Jazz and Country, and has all the illustrations PLUS a CD with 21 recordings from amongst the heros.  You can see it at Amazon at

The recordings are very old and scratchy, but really truly authentic.  I enjoy them.

Ooooooooh! Thanks, Ron. Very exciting. 

I have this one and the Heroes of the Blues with 36 cards (texts by Stephen Calt), bought in Paris 10 years ago. Back Front
