Previous CA blue plate with yellow letters: 1939, marked: California Worlds Fair.

There are people locally that make repro's of black plates in either aluminum or plastic. Some people that have the newer white plates have repro black plates made with the same number, then install them using the correct month/year stickers.

Is it illegal? As long as the license number matches the registration...who knows?
