Well for one, you can tell Teds signature, and secondly I have the original box that it came in with Teds address still on the box. I am 100% that it is an authentic signature. I purchased it from a reliable source. I would not sell anything and claim it to be authentic if I knew or had a doubt it was not. I am asking $150 for the arrow. I have seen them on Ebay go for as much as $200
