I have been using stationary as artwork on my walls for years, especially back in the day when I couldn’t afford real art. The great thing about it is you don’t feel bad for getting rid of it when you’ve grown tired of looking at it. I currently am a little fixated on mid-century design and I got just a bit excited when I ran across this Charley Harper stationary (on clearance) at Anthropologie.
Another idea is when I visit art museums I always go to the gift shop and check out their postcards. Once I get bored with my Charley Harper prints I plan to exchange them for some cool Barnett Newmann postcards I picked up.
