Mad THE COMIC BOOK #7 from 1953 has an omission which would be glaring, if not for what took it's place. It's got the usual four stories all written by Harvey Kurtzman and drawn by Bill Elder, John Severin and Wally Wood...but no Jack Davis! That doesn't stop the multi talented Kurtzman from filling the comic.
If you've been digging his covers, just check out Kurtzman's "Hey, Look!". One page comic vignettes by a true master.
