As long as we can remember, our family has had a subscription to The New Yorker. When we were too young (or perhaps too disinterested) to read the articles, we still loved to look at the great cover art. Our mom would save the illustrations, and was way ahead of the curve many years ago when she decided to give them a proper showcase.
Our small downstairs bathroom needed some oomph, so she picked out her favorite covers and created a wallpaper out of them. It still makes us smile whenever we see it, and we think it's a great idea for anyone who has trouble getting rid of magazines. And if she gets sick of any of the illustrations, it's fairly easy to switch one out for any of her new favorites.
If The New Yorker isn't your cup of tea (yes, we realize this is AT:SF, after all), why not substitute with one of your favorites? Or maybe try this idea using pages of text, instead.
