Marc Jacobs has designed several t-shirts, hats, and totes with Al's face on them, and they are on sale at Marc Jacobs stores for only $15-20. All proceeds go to the Climate Project. So support Al, his cause, and of course, Marc Jacobs and pick one up! I love this one. If only there was a store in my area, oy.
You can check out the other merchandise by going to the Marc Jacobs website and going to "Special Items". Can't directly link, sorry.
