BetterWall.com has partnered with over 20 art museums around the country to salvage and sell their used exhibition street banners. They give a portion of the proceeds back to the museums, and damaged banners are destroyed and recycled for the raw materials. Bonus: they've already kept over 10 tons of vinyl out of landfills in the past year alone. Bonus2: you have to love an ecommerce site that has "Provenance:" as one of their descriptors.

Now, if they could just convince Kate to get in on these!
