Here's a fun house ad from 1942. The use of the 'film strip' technique for the Boy Comics is pretty novel here, and has a real Showcase #4 vibe. When that was used for the first time? The copy is quite terribly lettered as the spacing makes it difficult to read. The Daredevil Comics ad is interesting, as it is pre-Little Wise Guys by just a few months. I also really like how they proclaim that the editors have signed the Pirate Prince and Dickie Dean to 'lifetime contracts'. Those strips were terminated in 1945 and 1947, respectively.
