The license plates in Wyoming have a bronco with a cowboy riding it. The bronco has been on this license plate ever since 1936.  Today the license plate has a bucking bronco with its rider on top.  In the background, there is a plain in front of mountains.  On the license plate next to the rider and bronco on the left, there is a number.  That number is the code number of the county where it was made.  Air national guard plates use all even numbers, but Army national guard plates use all odd numbers.  Wyoming allows personalized plates but no personal designs.
