Olly Moss and Spacesick are both For Real

Retro-futurism is a word (two words?) for chrome jet packs and art deco rocket ships. Retro-modernism is drinking a martini in the Jetsons' house. Alt-history is what happens when Hitler wins WWII and JFK is up for a second term but now America is Germany's bitch. 

So what do you call posters and book covers for modern movies made to look old? I think it's called Brain-explosionism

The books are from Spacesick.

The posters are from Ollie Moss.
