So in a trade I recently acquired an Elite Throwback Threads Ozzie Newsome Tony Gonzalez /199 Jersey card. I noticed the Gonzalez has some sort of a faded blue streak going vertically right across the patch. I can get a pic as I know this is not much to go off of, but I thought it was a cool patch and have no clue what it is. If you have any patches like this pleassse help me identify what is on this one! Thanks!
