I have here for sale one brand new and sealed copy of the Super Nintendo game Super Mario Kart! I'm not the original owner of this piece, but to my expert eyes, it appears to be 100% authentic. I have taken close up pictures of the vent holes for you to see. H-seam is obvious. This piece appears to have been stored somewhere for many years, but it is in FANTASTIC condition and will make a great addition to your collection. One of the very best games of all time! Any questions, please email me and I will be happy to answer! Thanks!
