Do what Denise of The Painted Home did and repurpose it into a wall shelf. She sawed off the axle and wheels and inserted a couple of wooden shelves. Screw into the wall and you've got an instant retro spot for display. Denise has her red wagon shelf up in her kitchen. Head over to her blog, The Painted Home, for more photos and details.
