I'm curious why anyone is bothering with a fake license plate sticker? The penalty for no front plate is a fix it ticket in CA. The penalty for a counterfeit license plate is a misdemeanor or felony depending on cop/judge/DA/whatever. The best case scenario is they ignore the sticker and cite you for no front plate. Worst case is you get a citation for forgery of a license plate.
You're better off contouring the plate to your bumper without flattening the raised letters and using adhesive to hold it on. You'll at least have a real plate on the car.

Having a sticker of your plate on the car isn't going to eliminate the meter maid for citing 'No front plate" tickets. You're better off leaving the new car registration paper in the lower corner of the window.
