because I love those really old helicopters, sci fi and fantasy air battle scenes, and I wanted to let you know of a website I just came across that only features pulp magazine cover art

 https://pulpcovers.com/  there's 23 pages just of this artists other work. 

If you think the flying submarine is goofy, well, this artist was making a lot goofier stuff to get kids to buy these magazines, like vampires, combat skeletons, silver sinned gremlins, very ridiculous stuff that was a lot like Flash Gordon, or Edgar Rice Burroughs creations, and Red Skull, Capt America's adversary
