Welcome ALCZ!
Love the art deco train poster!
I collect horror and sci-fi myself, but am inspired by all art periods and styles.
I think your poster is from 1928 by Pierre Zenobel. I don't know much about advertising posters, but someone on here might be able to help you with more info about it if you're interested. Just ask around.
Enjoy looking through the posts, it's a great place to find a lot of like-minded folks!
