Funny tag on fender- what is it?

I think that we have opened a can of worms. I worked at a dealership in 1968 and ordered my cuda BB car. When it arrived it was obvious it was a re-paint. You could see on the "A" post where the two paint jobs joined. And there was no extra inspection tag on this car. Why? I think all we can say is that the factory was very inconsistent.
