Creepy #1 with that iconic cover by famed artist Jack Davis is keeper, and the inspiration for many artists over the succeeding decades.
For the record, the book Jim Warren is holding is the Comic Book Artist edition from which the expanded Companion evolved.
Love the work of Mitch O'Connell, an artist with a bold and lively style. When I stumbled across the ad above for this book Mitch O'Connell - The World's Best Artist, I was entertained by the powerful homage to the vintage Creepy classic.
And I even found another swipe of the Davis art from a guy named Tom Neely.
Here's a nifty one from William Stout who gives a shout out to his inspiration.
And finally here is another example by Jack Davis himself, riffing on his original design, but this time putting Frankenstein's Monster front and center instead of Uncle Creepy.
A somewhat off-center rendition served as a cover to this price guide.
