Am I too old for all these sports posters?

yes

If you still enjoy it, then there is nothing wrong with it. Sometimes we grow out of things, sometimes we don’t. If you feel like you’re too old for it and want a more "mature" room then take them down and save them. See how it feels with the walls bare for a while.

hey, if u like them, then keep them. my BF has heaps of posters, he loves cricket. my other mate (whos the same age), has posters of cars etc all over his walls. its just the personal preference i think.

If you like sports there are ways to incorporate this theme into a more mature look. The ladies will think you are more of a man than a boy…(you know what I mean).That way, you can have your cake and eat it too. Your room should reflect your personality and likes, but you can achieve it in a classy more sophisticated way. Here are some links with some ideas.

stack your posters in a pile with velum paper between them, store in dark closet and wash the walls with TSP and paint or wallpaper.
when you’re ready to revisit the poster bit again, just pull them out and post away.
Posters become more valuable as time goes by, you’re to Young to have value in late posters, but if you have actual old collectors posters, they are valuable and hang on to them.
