Up for you consideration I have John Elway's Quarterback for the NES, Nintendo Entertainment System.
The cartridge is a 3 screw, with the Gold Nintendo seal of quality label.

The pictures are of the actual game that you will receive. Please examine carefully.

Additional pictures are available upon request.

I have opened this game and verified that it is genuine.
I have cleaned and polished the cartridge pins and left a thin layer of DeoxIT which improves conductivity, cleans, deoxidizes, lubricates and helps to protect the pins and reduce wear and abrasion.
The outside of the cartridge has also been cleaned to the best of my ability to remove any stickers, writing and or dirt and grime.

The game was tested and plays flawlessly on my original NES console.
The game comes in a new transparent plastic protective sleeve as seen in the pictures.
