car service notification postcards, they were the way to pester everyone on the dealership mailing list, and drum up more business with the lucrative oil changes and tire rotations

crazy, that the above 4 were given to me by a friend who came across them recently and rightly figured I'd never seen such a thing and would want to post them. I forgot, but this past weekend the below examples were emailed to me by Maurice who came across them when going through stuff, and they were sent to his parents

So there it is, post cards from the late 50s to the mid 70s didn't change a hell of a lot
Thanks Maurice!
