I'm not sure that art deco is really the right term but there's definitely a 30s/40s poster styleI find quite attractive. You also see it wit a lot of travel/national park/etc. posters from that era.
The National Parks poster style is often called the Work Progress Administration (WPA) style. There was a series of these done for astronomy education in the early 2010's that are wonderful examples of the style: https://www.wired.com/2013/12/nordgren-planetary-posters/
