Good luck with M&N. They aren't even sure of what jerseys they actually made. Lakeshow2 is an authorized M&N overstock dumper on eBay. His stuff is legit, but variety and sizes will be limited.

Lots of fakes...just like the Reebok NFL authentics.

What's funny is sometimes eBay shuts down auctions of peeps selling legit M&N jerseys on the secondary market. So the seller will occasionally be forced to hide the tag and not mention the manufacturer's name.

You'll need actual pics and then try to compare to a legit M&N jersey.
