Black frame on the photo above is not part of a poster. The paper is thick and overall quality is great. I've pinned it to an old painting frame that matched it perfectly. What I noticed is that its dimentions can change a bit depending on humidity in the room. So mind that when you attach it.
The quality, detail and general awesomeness of this poster is just amazing. Never before have i had a poster with such quality in my room. 10/10 would buy again.
