It appears that Rolling Stone has "Photoshopped" an image of Mario into that of Luigi.  Scandal!  As Frank Cifaldi notes in his Gamasutra blog, someone at Rolling Stone took an NOA press release screen shot of Classic NES Series: Super Mario Bros. for the GBA, changed the color scheme on Mario, and put it up in their "Year of Luigi" photo gallery.  Feel free to take a look at the images and compare them to the original screen shot, viewable on the TMK Classic NES Series: Super Mario Bros. page!

For shame, Rolling Stone.  For shame.

(You might remember Mr. Cifaldi as the writer who the mystery of the release date of Super Mario Bros.  Thanks again for your true journalistic work, Mr. Cifaldi!)
