How many posters of miley cyrus do you own? I own five. One for each wall of my bedroom and one for the bathroom. Oh wait, I forgot about the one on my door – six. My prized is my "miley cyrus Rocks" poster where she is holding a guitar upside down behind her back (you would have to see it). How many do you own, and which is your favorite. After looking around, I learned — 8. I love Miley Cyrus I'm obsessed with her. My prized one is when she is a wearing a purple short sleeved shirt and jeans and it has her autograph oon it. I didn't get my prized poster in a concert I got it from a magazine.
