Origin of the Sweeney Todd caricature?

Was the "small, flamboyantly dressed angry man" who represents Sweeney Todd on the original album cover created for the show, or does he predate the play? I know his accompanying Lovett caricature is original, due to its resemblance to Angela Lansbury, but I've seen the Sweeney caricature show up in a number of other places, always without the razor, as a piece of kitsch Victoriana. (Notably, he's on a Collective Soul album cover.)

I just saw an interesting woodcutting from a Ren Faire featuring the caricature, and while I missed the opportunity to buy it, I was left wondering: does that image predate the Broadway show, or has it seeped into public consciousness since then?

He indeed based it on an antique woodcut and created the Mrs. Lovett drawing to accompany it.

Thanks, Kad! That explains a lot.

I've seen the drawing (meaning the man, but without the Sweeney Todd embellishments) in other media, but I don't think I've ever seen the actual original woodcut.
