NEOGEO Neo Geo SNK Logo Light Sign Promotional Item Novelty Arcade

I impulsively bought this about two years ago on another flea market site.
Although I purchased it, I ended up not using it, so I am selling it.

It is an interior light, possibly a promotional item.
The surface is clean, but there are scuff marks on the back that look like they've been rubbed. This was how it was when I purchased it.
(Please refer to the images.)
If you are concerned about this, please refrain from purchasing.
I have confirmed that it powers on before listing.
The cable is USB.
It looks great when lit in a dark place, and I think it would look even better displayed with other merchandise or arcade cabinets. How about it, fans of Neo Geo and arcade games!
