Custom tradeshow backglass
There was a local company (Possibly Good Displays) that would convert a regular commercial pingame into a trade-show booth attraction.
Years ago, years apart, I picked up these as parts machines. Both were Bally Six Million Dollar Man. (Notice the extra two display windows.)
One was for Champion Spark Plugs and the other is Opportunity Tire promoting Fiberglass belting.
Pictures to come.
