Up for sale is this Classic Nintendo Wheel of Fortune Cartridge & Booklet, Untested

The cartridge is untested but visually appears to be clean and in good condition. The booklet is stained all the way through from front to back, top to bottom at the binding. It looks like some liquid was spilled on it and it soaked through. The booklet is still usable, the pages turn and are visible, they are just not perfect.
