I know this is an old thread and I'm a lot younger than most of you, but I had loads of posters on my walls in the early '80's, like Duran Duran, Human League, Depeche Mode, my favourite band UB40, and the back of my bedroom door was covered in pictures of Bryan Robson, my favourite Baggies player.
I'm always amazed how much stuff I got in a tiny box room, I had my bed next to the window which my cat loved! A wardrobe, dressing table cum desk, bedside table with my lamp, book I was reading and radio, mom's old stereo record player and a beanbag! You could hardly move in there, but oh! I loved my teenage bedroom!
