While discussing horrible things (movie related, of course) with Professor Kinema one sunny Sunday, he tossed this replica of Eerie No. 1's 24-page ashcan, 1st edition, over to me. While I vaguely knew about it, I had never seen this pocket-sized first issue, which was quickly slapped together in 1965 by Warren Publishing, and distributed briefly to lock in the magazine title's name before a rival used it, or so the story goes.
Here's the entire ashcan for your edification pleasure (although the stories were pulled from Creepy issues). From what I've read on the web, this replica indicates it's from the 1st edition because: on page 18, panel 5, what should be recognized as the back of a bald-headed man in the upper left corner shows only black; and in the margins of certain pages you can see the paste-up instructions. Bootleg copies abound, making it a difficult item to purchase without authenticating it first. Warren complained about the bootleg copies in Creepy No. 81 (see page at the end).
