Gary, If you are in Roanoke...there is an antique store on Williamson road that is having an auction today...and again for the next 3 Saturdays...there is alot of car and gas station stuff in that shop....I recall ( 2 or 3 ) boxes of license plates and frames ( they were on the floor near the front windows...if you go there )
...you may want to check it out....and maybe get lucky in finding the dealership frames ....
..check it out
