New Jersey Official Booster License Plates

OFFICIAL BOOSTERS This is an odd category - it consists of various random items that were bolted to cars, but not strictly for New Jersey state registration.
I'm calling them booster plates, but since there are some from state plate blanks, and some used by law enforcement, I'll classify them as "official" boosters.
