Collectors should be aware that there was a NEAR EXACT REPRINT of WHIZ COMICS # 2 (# 1),  published in 1974 under DC Comics' FAMOUS FIRST EDITION line.  Originally, the comic had a stiff outer cover identifying it as a reprint.  When the outer cover is removed, it is NEARLY IDENTICAL to the original book, except that it is OVERSIZED 10" long and 13 1/2 inches tall, and the original says "Gangway For Captain Marvel!" on the front cover..  There have been many instances over the years where a non-comic collector has been fooled by one of these reprints.  When I owned a comic book store, I got at least one call per month from someone with an oversized reprint of either Action Comics # 1 (1st Superman), Detective Comics # 27 (1st Batman), Sensation Comics # 1 (1st Wonder Woman title), Whiz Comics # 2 (# 1) (not identical to the original, but not identified as a reprint either), Batman # 1, or Superman # 1.

A genuine Whiz Comics # 2 (# 1)  will be the same size as a normal Golden Age comic book, which is slightly smaller than a normal sized magazine
