As someone above suggested why not start with license plates. About 35 years ago I was salvaging old VWs, naturally I was after the parts, but the first thing I took off of them was the licensed plate.
After I married Cindy and inherited her very large garage I took all of the licensed plates and put them on the rafters in alphabet order. Just the other day I took a good look at them and found I only needed eight more of them to have all 50. I thought that soon I would post here asking guys to send me a one of the eight, and I would send them a Missouri plate.
Why don't you do this? It is an easy way to build your collection, plus getting to know the greatest guys who help each other, that is what this site it about. Maybe I should post the eight plates I need.
