Hello,
Some years ago i bought in a garage sale a Vectrex cartridge with handmade sticker “Mail Plane” and a lightpen...played with it....years passed....almost forget it but i saw recently that the cartridge seems quite rare and had never been commercialized.
I would like to sell it...but i don't know how much it could worth...
This is a videolink showing the game...
