Answer 1

American style

Answer 2

"How it's done" - an artist-designer who knows how to draw is taken, and he is given the task of drawing it.
The name of such a "style" has nothing to do with how it is done and will not help to achieve such an appearance for someone who cannot draw.
In principle, this is a stylization of advertising posters of the thirties and fifties of the twentieth century.

Answer 3

A few years ago it was very popular on the web , often this style was then called "vintage" like grunge texture like for photoshop or vector. Well, know how to use these tools.
You can always see how others are doing by querying "vintage" "grunge" on any stock, design resource or just in Google. Yes, just on freepik.com you can download the vector you like and parse it, thus understanding how people implement these effects.
