Just ran across this website of a comics scholar who has posted a bunch of cool old comics and other illustrations…
Tons of great obscure stuff… check out this advertisement by Winsor McCay… and “The Virtuoso”… and a bunch of great Barney Google and Happy Hooligan strips… and a nightmare… so much cool stuff.
As you can see from this image, Ken Avidor has been drawing cartoons for an awfully long time.
