Old Posters: Awkwardly Entertaining or Totally Creepy?

I was looking through Google images for some examples of old timey movie posters, preferably romantic westerns (don't ask, yes I am working on a project). I didn't really find exactly what I had in mind, but that's beside the point. I found these images of old posters. But I can't tell these days what is really old and what's just designed to look old. Does anyone know if these really exist(ed)?

Interesting.
