Oh yeah, Struwwelpeter, "Little Suck-A-Thumb." I've seen that reprinted somewhere. There was also "Max und Moritz," by Wilhelm Busch, who I used to have in a Dover reprint, until I decided to free up the shelf space. It was a whole volume of Busch's comics, and practically none of them were actually humorous. Max und Moritz trick a miller by cutting a hole in a sack of grain, so he playfully gets even by grinding them up with his mill wheel and feeding them to the ducks. (Since then, I've seen a two-volume set of a whole bunch of Busch's stuff, but always at a price I could resist. The Bibliopath in Norfolk had the pair for years, even after changing management and the renaming of the store to The Bibliophile -- I'd be surprised if they aren't still there.)
