Why does Shrek resemble this illustration from "Max und Moritz" (1865)?

This is an illustration from the 1865 children’s story Max und Moritz of a grain mill with an output chute featuring a grotesque decoration–which looks a lot like the character Shrek:

The same mill was depicted in a German film version of the story: Mill scene from Max und Moritz (1956) - Imgur

Was the cartoonist William Steig (who created the book Shrek! on which the first Shrek movie was based) influenced by Max und Moritz? Or was this some traditional type of monster/ogre that has historically been shown as looking like this, with a bald head, large mouth, and horizontally elongated ears?

The resemblance is extremely vague, without you saying anything I would not have guessed Shrek out of seeing that.

Aside from the ears (and being “a face”), it’s even less like the original Shrek from the books which has a much cruder face, a round bulbous nose, a pointy head and hair. That said, I guess it’s possible that Steig saw the comic/film and either consciously or subconscious included the ears as being pretty nifty. The book is from 1990 so plenty of time for the author/artist to have come across either.

It’s like grey aliens or fairies. There’s a conventional “ogre” description/classical look of which specific examples are derivative.

They don’t look the same to me.

I thought the animated Shrek was based on Maurice Tillet.

They may have both been inspired by people with microcephaly

Given the number of potential causes, it probably used to be a common sight. Better medical knowledge will have reduced several causes

Wow, Tillet really did look like Shrek!

Tillet had a different disorder: acromegaly.

Looks like a Greek mask to me

except for the “ears” attaching it to the mill

You’re right, the book version of Shrek is very different. I guess, in my mind, I was inadvertently comparing it with the movie character: Mill from Max und Moritz film (1956) and Shrek (2001) - Imgur

To me, what’s definitive about Shrek’s appearance, as distinct from any other depiction of an ogre, is that his ears are conical. All of those other depictions, from both of the Max und Moritz sources and from the Shrek book, appear to have normal ears (or at least, as close to normal as the art style permits) on the ends of stalks (which is, admittedly, a deviation from the ogre norm, and potentially interesting). The other ears don’t look like the sort of thing one might extract a taper candle of earwax from.
