For over three decades R. Crumb has shocked, entertained, titillated and challenged the imaginations (and the inhibitions) of comics fans the world over. The acknowledged father of ''underground comix,'' Crumb is the single greatest influence on the alternative comics of today. The three companion sets of trading cards - Heroes of the Blues, Early Jazz Greats, and Pioneers of Country Music - have all been sought by collectors. Although, they are currently back in print as individual card sets, this is the first time they are being published together in book form. A biography of each musician is provided, along with a full colour original illustration by underground cartoonist and music historian R. Crumb.
