Nintendo appears to have mistakenly used a fan-made render of Mario on the Super Nintendo World site
You might be rendered speechless after a gaffe Nintendo just made on their newly-launched Super Nintendo World website. A loading icon for the page currently features a render of Mario, however, that artwork doesn't belong to Nintendo. Twitter user uJidow claims that Nintendo mistakenly used their render of Mario--not the official one. The differences between the two are quite negligible, with uJidow's appearing to be modeled after the original. The image on the left is official and comes from New Super Mario Bros. U Deluxe, while the fan-made one is on the right. You can see that Nintendo is using the doppleganger Mario, as the one on the loading page has brighter eyes and shinier brass overall buckles--just like the fanart.
