Here is a link to the car rear window decal that we like. Also here is a link for a business card holder with a magnet on the back so it can be mounted to your car.
You can get the car decals (see-through so they don’t interfere with your rear-view vision), at many sign maker companies.
We know one with nationwide francises at www.signarama.com.
