First off, I'm almost 100% certain this is real. Why would Tebow have an autopen? Various different widths within signature, and change in pen pressure. Signature can clearly be seen on top of photo. Lastly, it looks just like Tim Tebow's signature. What causes the jagged lines on parts of the signature? I was unable to find any other of my autographs that had a pen that caused jagged lines similar to this. Did this sharpie just have some jagged felt? Any help is appreciated.
