Perhaps some sort of puddy adhesive that's save for walls. I don't want to nail directly through the poster though
Does anyone know how to put up a cardboard poster in your room without nailing through the cardboard?

Frame it. I'm assuming this poster is worth something if you are not willing to pierce it that what I did.
I have a wanted dead or alive poster from 100 years ago for my great grandfather and its worth a lot so I framed it0
