I don't see anything wrong with it. It looks completely authentic. There is no problem with a double-sided hangtag. Coach started using them in the nineties.Could I get another look at this Willis bag? I started rehabbing it, and I'm not so sure it's authentic. After I gave it a bath I saw it had a double sided hang tag, so now I'm totally kicking myself. (I know it's not a sure sign, but it doesn't necessarily look good either.) But if it is a fake, it's a ridiculously good one. The creed is M5B-9927
Here's an album of the pictures.
