Bill,
I knew I wouldn't have to identify the location of where I took the picture of Bob. Bob was quite active in collecting from the mid-1980s and through the 1990s as I recall. He was my main competitor for SL Cabinets during that time. Then came two more gentlemen, Tom B. and Scott B., to increase the competition. Seems that some people just get in the act when you're trying to corner the market!
It's been many years since Bob sold his collection, got divorced, and left the country. Exactly where he went and where he might be today I don't have a clue.
