What kind of design is this?

[Sigurd Setsaa]

I recently saw some of Olly Moss' work on a project for a game, and I saw these promotional posters he made for it. I'm wondering what this type of design is called. It looks to mimic old American infographics from around the 1950-1970 era.
Help would be appreciated.

Personally I'd class that as a modern interpretation of Americana ..... with instagram filters applied lol

It's graphic design or illustration, I don't think it needs a specific label attached.

It's just that I've seen this type of design before, but I can't remember where. It reminds me of old American forest fire posters. I'm making a design for a tea brand and I want it to have a retro design in that vain.

Graphic poster illustration I would call it.

The composition is derived from old Art Deco travel posters.
