Light up Marathon desk sign

I found this in a storage unit I bought. I have not been able to find any info on line. It lights up and is a desk piece I think. I believe I remember the local Marathon station having one when I was a kid but I don't remember for sure. Anybody seen one of these? It is an interesting little piece and am just looking for info on it. Not planning on selling just bugs me when I can't find it on line. Thanks.
