This is what I am imagining for you.
Cheap and effective. I have one in my living room with a sweet poster I got at a local art fair. It stays put unless I accidentally bump it, then sometimes the poster actually falls out! But most of the time I don't have a problem with it.

If you really love the poster I would say also consider getting it mounted. You can go wood mounting or foam core mounting, foam core being the cheapest way to go. Looks great on the wall, though.

I think this looks like a swell idea, although it didn't get great Amazon ratings. It's like a scroll on your wall. I guess I can see how it would be a little finicky, but I do like the idea. It's not as labor intensive as mounting it in a frame (well, 'labor intensive' might be a slight hyperbole...) but it's better than just sticking it to the wall.

Well if you want to adhere directly to the wall you should use these. However, I think the poster frame is a better idea because it protects the poster while keeping it flat and also won't stick to your wall.
