To many of us who knew Gordon he was a dear fellow collector. Over the past could years he has sold much of his collection off. Much of it to us here at GDC. I believe his handle here was "Floridaguy".
Never had the chance to meet Gordon but he was an active collector and contributor to this forum. Bought a few things from him when he sold much of his collection a few years back. If I remember correctly, he was in the restaurant business down in Florida.
