True Classic
In the US each state has their own license plates. But all of them follow the same federal requirements on size and layout. That also allows individuals to request their own plate number (custom sayings, etc). Beyond that the states can create different images for the background, special editions, etc, so long as they meet the federal rules. Some states have gotten really out of hand making all sorts of special edition plates. Mostly to honor a particular groups of people, environmental situations, or other causes. But a lot of them are just ridiculous. I kind of wish there was one standard for the entire country.
