Drove to Pittsburgh today to pick up a Bally EK that was a Professional Pinball conversion. If your unfamiliar with these, see this link:
The guy between the 2 chicks is mirrored so you hopefully see your face in the mirror when playing it. When I picked it up I noticed a face glued to the outside of the backglass. Peeled it off and asked "who is this dude?". Seller had no idea and never realized it. So he's been looking at this guy's mug for the last 10 years every time he played it. I really tried not to laugh my ass off, at least the mask I was wearing hid some of my amusement. I give the guy credit for trimming the pic perfectly to fit the BG.
