Below is a Calvin Johnson autographed jersey I bought but hasn't been shipped.

The seller has a perfect ebay seller rating and guarantees the signatures are real or 110 percent money back.

The loops at the bottom are bigger than some of the other autographs I've seen and there is no "Z" at the end which is in some of the signatures and not in others.it also looks to be more polished and not as messy as some of the other autographs I've seen.

Below is the only autographs I know to be real as CJ sent them to a professional golfer. Other than that I don't know anything that is confirmed 100 percent authentic.

What do you guys think? Does anybody have any Calvin memorabilia that they got signed in person or know is 100 percent real?
