Mets by the Numbers

I've seen ebay sellers use the term "authentic" in different ways. Sometimes, an ebay seller uses the term "authentic" to describe an actual or "legitimate" jersey worn in a professional game. Sometimes, the ebay seller uses the word to describe a brand name, referring to jerseys made for the consumer market that are almost visually identical to the real thing and made of the same fabric, but with small differences such as the tagging, tailoring cuts, etc. Sometimes the seller is vague enough, (intentionally or not) so as to confuse the matter entirely. The size "42" throws this off. If it's a fake, however, then all logic goes out the window, and anything is possible. Maybe the seller made up a size 42 tag, but the jersey itself isn't physically a size 42. Any pictures? Is the auction link still active?
