Tijuana bibles from the '30s (the original rule 34) mixed in with some then-recent material. And no, I don't have the other two.
I should apologize in advance for the quality (and lack therof) of these comics.
The source material can range from decent to terrible in a matter of only one or two pages.
Wait, why am I still typing shit down? Just read these for yourself and make your own conclusion.
The most recent thing in this comic is this spread featuring Cuthbert Crotchpheasant (Google him). Drawn by animation veteran / cartoonist Ken Landau, under the pseudonym of "Vern Kent" (unsigned here).
and there you have it
You can find this on Libgen, just use a proxy
Thanks for reading and (most likely not) masturbating at the same time
