I am talking more about knock-off wannabes. He made the world safe for unfettered prurience; where his brand (at least in my opinion) within a fairly broad framework still managed to retain a sort of a specific aesthetic focus. I guess I prefer a fetter. It's like most cultural breakthroughs; less talented wannabes can ape the style, but have none of the attendant panache.
Many people can steal Warhol's/Magritte's/Rothenberg's style, but can't bring anything additional to it. That's what I feel about many of Crumb's lessers. Of course, I haven't really followed comics closely since the 80's.
Oh hell, what do I know, I am a math guy.
d/dx(e^(x^2)) = 2xe^(x^2)
That I can say with confidence.
