I have a fox hunt water color that I picked up at a thrift store (which has my riding crop hanging next to it). I have one wall papered with Victorian-floral scrapbook paper (all in reds, pinks, and tea-stain beige). I'm taking the fox hunt picture with me when I move in with C.
C has a penguin colony photo (which we're planning on sticking a Tardis in the distance of the photo so it looks like the penguins are running away from the Doctor), and a wall covered with cyber-influenced magazine pictures he cut out of old issues of Wired. He also has a bamboo flute hung up on the wall. He asked me to find posters or pictures to decorate his walls, as he finally noticed they look rather bare.
My mother is giving me her "Alice in Wonderland" Tenniel prints (originally sold at Cabbages and Kings back in the early 1970's as a coloring book). I don't think C would care for those in most of the house, but my Library and the future nursery will definitely have them.
