There is something about Charley Harper's work that sets me aflutter. And I am especially partial to his commercial work for some reason (as opposed to his fine art prints which are lovely). We have the Sierra Range poster framed in our bedroom and I find new shapes and lines, angles, and connections in it all the time. The poster, and several others, are available for practically nothing at the US Government Bookstore. Shipping isn't swift, but the price is right. So, if you are looking for holiday gifts or you yourself want to collect some Harper, but can't afford a print, this is the way to go.
One word though, the large posters really are huge and they aren't standard frame sizes so you'll end up shelling out bucks for the frame. Still, a huge, colorful fun way to fill your walls.
Last year I managed to snag this memory game and more at Old Navy, as seen here on the always enjoyable ohdeedoh.com:
