I do have a fondness for some of the EC comics which aren't available here, namely "Shock Suspenstories" and "Two Fisted Tales" (which is neither crime nor horror). I do enjoy "Guns for Gangsters" which is in the crime genre but really isn't typical, and I have read my share of "Crime Doesn't Pay" which is the flagship title of the genre.
Harvey has some of the titles that had some of the most extreme horror stories and I can't say I really care for them. Charlton published some nice early Ditko stories and "The Thing," and it is a book I can generally recommend. A lot of ACG is junk, but it is entertaining junk.
There was a blog site at wordpress, that is no longer around. They had EC, Marvel and some other popular
comics from the day uploaded there.
I loved EC from what I'd read. I also happened to download and read ShockSuspenstories. What great
artwork. It was eye opening for me at 37, to see that there were comics being sold in the early
50's, that dealt with rape, racism, murder etc. Unbelievable!

Also really enjoyed reading Weird Science.
I know "Crime Doesn't Pay" was extremely popular. I plan to check out some of those comics.
The stories weren't all about mobsters and gangsters, were they? I'm guessing they wouldn't
have been as graphic, or as extremely violent as EC's titles were?
I did some of Harvey's horror titles, like Witches Tales, Tomb of Horror, Chamber of chills.
