R.Crumb or Robt. Crumb or Robert Crumb. My first exposure to his stuff was the Cheap Thrills album art for a great Janis Joplin record which my Mom owned. I had never seen art like that when I was 12 years old. I forgot about him but his work kept popping up throughout my life, even on blotter acid. The dude is just incredibly prolific and his style is all his own. Just look up robert crumb
