Oops, let's try that again, forgot to add the image.>>99867306>I got the impression that he started out a bit smaller too, was gradually depicted as larger over time, then they decided to make him smaller again
Yes. Oldfag here, started reading late 1980s and watched some of this. Here's a sort of timeline I found online, and they could be described as—
early 1950s: started out small and short
late 1950s: got tall and thin, more like a high schooler
1960s-70s: shorter again, often sort of monkeylike in posture
1980s-early 90s: bulkier and taller, more like a high schooler again.
mid-90s: resigned for cartoon (Beano switched to match, so suddenly it was a shock), huge head, bigger eyes, smaller nose, mouth position moves up so far it often looks like it's behind his eyes (now that's a nostalgic design, but in 1995 we older readers thought WHOA wtf?!)
Around 2010: redesigned again for newer cartoon, much more obvious TEETH
And then THIS>>99866054
is the current CGI cartoon, which uses the tall late 1950s design quite directly. Odd choice, but plenty of history to it.
