I almost missed this post, Mike. Thanks for the info, and I know you were close to him. One of the most interesting days of my entire life occurred when I delivered two pins to Joe's place. You were there ! I had seen many large collections, but had never entered a home that was essentially all pinball machines. Also purchased a Gottlieb Liberty Belle from Joe back in the late 90's. A nice man - always interesting pinball conversations.
