Not sure why this thread has so much trouble ID'ing Hermes ties. The fakes are usually very obvious (no accent mark, price embroidered on the tie). Also, I've handled real Hermes ties where the thread loop isn't showing—I wouldn't let that detail be the deciding factor.
I think its real too. On the subject of IDing Hermes, I once bought an Hermes H belt on ebay with a guarantee that its authentic, which of course I didn't trust, so I brought it to the
Hermes store in Manhattan and the manager there told me that they never have id cards with their items so its fake. Now take a look on ebay and see how many you
can find without cards.
