Dyer's Auto Sales Greenfield Indiana Advertising Badge Nameplate VTG
This is what they put on the back of a car or whatever to advertise to people where the car was purchased from.
It's not a sticker. It's much thicker plastic.
See pictures for condition details. It's in decent shape in my opinion but it's not pristine or perfect or anything like that. It's probably 6.3 inches long. I measured yesterday but I find remember the exact length.
