Somebody has too much time on their hands

The Missouri plate is fake.

I was pretty sure it was - it's been over 30 or so years since there was a black MO plate, and the "Show-Me State" motto on plates started in 1980.

Actually, that was the color scheme for vanity plates until the regular plate scheme was changed in 98, at which point the vanity plate color scheme changed with it. It may be fake, but the color scheme is not conclusive evidence of such.

Many artists want to express their patriotism, and Mike Wilkins chose personalized license plates to spell out the Preamble to the constitution in license plate shorthand. He contacted the state transportation officials of all 50 states and the District of Columbia to acquire them. After over a year of red tape he was able to come up with this creative homage to America. His project was thrown into limbo when a prison disturbance in New Mexico caused a temporary shutdown of the state's license plate shop, and it was delayed by Minnesota when the plate he ordered for the last half of common and the first half of defense (UN DE) was considered inappropriate. (Too much like undie). Nevertheless, he was able to acquire them all, and the above picture is the result. Notice how they are in alphabetical order and how he has abbreviated, condensed, split and substituted numbers for some of the words.
