Is your copy of Halo signed by Bill Gates?

Do you remember when Halo 3 was launched? That day was like Christmas for me. After a long slow burning build up the day arrived.

And so it turns out that Bill Gates sold the first official copy of Halo 3 to this dude on the picture. It was apparently the only thing Bill signed that day.

I do wonder if it really was the first copy sold as I'm pretty sure New Zealand was the first country in the world to officially open for business that day as we are a head of time zone ...
