When I ordered a shirt from the Amon Amarth website, the packet it came in included several posters. Makes me wish I had room to hang them. Maybe I should make room. Hard to do in a closet-sized room, even a 'walk-in closet'-sized room.
I've a map of Kalos, Johto, and Unova, and Adventure Time, Minecraft, and Super Mario Galaxy 2 posters. Also, when GameStop took down their big Pokemon Black and White posters, (Which weren't any pre-order bonus) I asked them if I could have the Pokemon Black poster and an employee gave it to me for free.
I have a ton of Hello Kitty posters!! I also have a bleach poster, and giant anime lifesize poster on the other side of the wall. It's about the size of a window. @w@
I have a Breakfast at Tiffany's and a concert poster. Because I have one big gigantic painting in my room, I like to be minimal. I'm hope to paint an Animal Crossing-related picture, once I find a new primer to make a new painting.
