Right, Top Notch 2 from January '40 had some nice one page splashes as I recall. Some pretty amazing stuff. I've found a lot of things that go against the prevailing wisdom of early comic lore . A lot of these things, like the 1 page splashes, are just because a lot these books, while they've been collected, haven't actually been read by some collectors. The prevailing wisdon for a long time was that Marvel Mystery # 4 was the first Nazi war cover but that was absolutely false, it was Top Notch #2 which was the first Nazi war cover with a swatzika on the cover battle scene. It took a long time for Overstreet to half heartedly correct this.... wouldn't want to devalue Marvel Mystery 4 now would they.
Let's not forget this page from Blue Ribbon Comics #3, January 1940:
A hidden gem!
