This was the 2nd plate I ever had, and was on a 1972 Audi 100LS that I drove during my college years.
License Plates
People collect all sorts of things (stamps, coins, postcards, baseball cards, etc). Why not old license plates?
Over the years, I have kept pretty much all the license plates that I have been allowed to keep.
In some states, the license plate stays with the car, in others, the plates go with the person. In the State of Texas, regular license plates generally stay with the vehicle, however, if you have a "personalized" (i.e.: vanity) license plate, then that plate goes with you to the next vehicle (or if you sell your vehicle, you can take off the old regular plate off before handing over your vehicle to the buyer)
On this webpage you can view the various licenses plates that I currently have in my small collection.
