This looks like someone just went to a local trophy store and asked for a plexiglass box and the cheapest engraving possible. I mean a Keith Courage game in a stupid block? How are people falling for this shit?
If they were real, that's probably exactly what they'd do. That's why provenance is key. There is no real difference between "real" and "fake" with items like this so you have to have a complete history.
I think they look perfectly real, or perfectly fake. Either way.
I like how the seller basically prepares the bidders to see a wave of identical "first" TG-16s. If 100 more of these show up next month he can just say, "Hey, I warned you."
If they were real then they were a good buy, IMO. If fake, probably nobody will ever know. But who needs ANOTHER copy of Keith?
