For sale is one Super Mario Bros. 2 cartridge NES-MW-USA with a replacement black sleeve.  Only the cartridge and sleeve are included; no manuals box or accessories.  The cartridge is authentic and I'd date it around 1990.  It has a nice label and some minor wear from normal use.  The back has the number 05 and a letter A in the back.  It boots and plays great on an original NES.  If you've never played Super Mario Bros. 2 it is unlike any Mario Bros. game you've played before.  Your primary attack is to pick turnips or onions out of the ground and toss them at Shy Guys.  Later there are dragons you can throw eggs at.   Princess Toadstool can defy gravity.  It's weird.  You have to try it.
