I created this posting 6 years ago. In that time, I have continued my search to find out what became of this ice cream business. Someone has a business website that has in it's history a Bob's Old Fashioned Ice Cream kiosk.
However, the sign has a new name after the person who bought it.
The original sign looked like this one.
This brought back memories for me. I liked that this business was so simple. Not alot of choice, but good product. I did find a franchise that was selling what appeared to be a simliar concept with the same name, but it was a cart business. I would prefer a kiosk style. I'm not sure if this concept could survive today. It seems people want more choice.
