License plates originally were not issued by the US government, but made by car owners out of whatever material they could use. Vintage New Mexico License Plates are usually plates that are out of circulation, but are more often plates from the earliest days of cars, primarily the World War eras or through the 50s to the 70s.
The description of Vintage New Mexico License Plates from the 70s was a cream-colored background with red letters and a native styled sun between the two groups of letters. New Mexico USA was at the bottom of the plate and Land of Enchantment was at the top. Back in the 40s, the background of the plate was yellow and the sun was to the left.
