Granted there would have been a screaming girl in the background or those 3 vignettes on the left but I only had the splash to work with. My main point was the subject matter being a werewolf rather than a closet full of spooky clothes.
Sadly, that "closet full of spooky clothes" was the beginning of tamed down covers for the series, and every JIUW following displayed actually even less "spookyness" on the cover. Prolly feeling the vibes from the approaching CCA censorship.
I think horror comics in general hit their height in gory covers about August of 1954, and then it was all downhill after that. JIUW just began a little early.
Look at the difference in the cover subject material up to issue #28, and then with #30 on;
