Those advertisements were found on The Propaganda Poster Store: https://propagandaposterstore.com/, which as the name implies has a large collection of propaganda posters, mainly focusing on war. This site happened to have several images that inspired posters in the series. Much like the mugshot inspirations I've discovered, these were discovered based on pure luck. I've also played the games many times and been active on this wiki for several years, so I've become quite familiar with the advertisements and the diary portraits featured in them. Usually I just go through archives of posters or sites with collections of images, like Pinterest (their image search tool, which lets you find similar looking images is a God's send!) and just happen upon them while scrolling through, and as I'm familiar with the media in the game, I usually recognize the inspiration on first sight.

I really love the "It Came from the Surface!" concept (I nice twist on movies focusing on creatures coming from the unknown, like space or from the sea). I have stumbled upon many sites and one that has a large collection of ads, as well as a great search tool, is http://www.vintageadbrowser.com/. I've also noted that sites that sell vintage posters usually have great collections. I'll keep that image in mind, but a question: are you looking for the kitchen setting, the shocked human, the machine or the whole concept?
