Quoted from ArcadeZone:I bought some old Pinball and Arcade equipment from a bar that went out of business recently and they had a Space Invaders Pinball Overlay which is in NOS or NEW condition. Willing to sell including shipping if anyone is interested.
That is not a NOS playfield overlay. It is likely a Classic Arcades overlay. Though based on your location, and what you are trying to sell, I would guess that it is a copy of a Classic Arcades overlay:
