MAMEWorld Forums - MAME Artwork: Official - What's up with Tempest cocktail?

I'm not promising anything, just looking for a new project. I can't figure out what going on at the edge of this bezel. There's a thick black squarish line around the edge and a thinner, curvier line also. There is significant overlap between the two lines and they are both black. I'm no graphics designer but that seems like an odd choice artistically. Looking at a photo of an actual machine it seems like one line has more wear than the other which doesn't make much sense if they are both the same material. I wondering if maybe one of the black lines is really some type of adhesive used to secure the glass to the wooden table top? Does anyone know for sure?

Also someone named Mikonos seems to have gotten pretty far vectorizing this back in 2012. I don't speak Spanish so I'm not sure what's happening on that page, but from other threads I've read here he seems to be persona-non-grata at Mameworld? Any work I did to this would just be clean-up (and adding woodgrain), so if there is a vectorized version out there somewhere that might be available, that would be preferable.
