I think that we should get stickers that go in the window as well as the bumper stickers. They could be oval with a white background, a black oval border, and the logo in the top left corner of this page.
Also I'd like to see a picture of a T-shirt with the logo on it.

I doubt that you can sell as many bumper stickers as window decals. Personally, I would never put a bumper sticker on my car.
