2002 Large Giro Pneumo Lone Star helmet with Lance Armstrong signed

Lance Armstrong came into the Giro office in Santa Cruz sometime in 2005 and signed for most of the employees. He signed this helmet pod and a hat for me. The hat is long since lost. This Lone Star Pneumo helmet and helmet pod are new and unused and both have been in various boxes while in a nylon helmet bag for all of those years. I have no authentication for this signature. I am not sure how that is possible. I was there, I sat across the table from him, I handed him the pod, he signed, and I thanked him for it. Take a good look, that is his signature.
