Hi
my rooms getting done and well i’m wanting some big football posters but if theres any place i can order online in the uk.

So im 21 years old and I want to redo my room. Since I can remember ive been putting up sports posters in my room, and no basically all 4 walls consist of Basketball baseball and football posters pennats etc. It looks pretty cool but am I too old to have my room like this?

I want to redo it but im not sure if i should whipe down the walls lol
