Looking for the decal/sticker in the pic below.
It has an engine turned kind of look to it.
Pic is of my car and it has been on the rear window for a long time.
I do not know the maker, but I do recall seeing them all over for all makes when I was a tiny human.
Let us know where and if you find someone that sells or makes them. So true, I remember the mid/late 70s seeing these style decals on a lot of the cool cars.
