The artist’s signature is on the bottom left, but I can’t read it. Let me know if you know who it is or have a closer close-up.
UPDATE: Andy Goldman pins the artist as Python Anghelo, the gentleman who actually designed the game and did the cabinet art (why was the poster art here not used for side art?), who passed away last year. Thanks again, Andy.

I think it’s Python Vladimir Anghelo (you can kind of see the helo at the end of the signature).

You mean the guy who designed the game and cabinet artwork? You think I might have known that!
Thanks, Andy.
