I've added the 1942 plate to the first post. The original California plate is lower than the default plate, so I tried to convert that design to the default size. GreenAid: I hope it's what you expected, if not, please tell me what I could change.
If anybody else has requests or suggestions for license plates, no matter whether they're based on any real ones or are fictional, feel free to post here and I'll see what I can do.
