I actually think this one is authentic. Now...if George Michael is like most stars, his autograph will have changed over the years. Many celebrities have various "styles" of autographs depending upon the timeline of their career. I'm no expert on George Michael autographs so I don't know how his autograph has evolved over the years. However, I recently purchased one that I'm certain is authentic, and while the one you show is not a perfect match with mine, it does show some very similar attributes which leads me to think that PSA got this one right. I've included a picture of mine so you can compare.
