I can appreciate Gasgeezer's experience for the exact same thing happened to me once at a farm sale when bidding on a globe. What turned out to be another bidder's buddy was camped out on my elbow actually pulling on my shirt during the bidding saying quite loudly to me so everyone could hear "It's fake...it's fake and besides it has a bad crack that is real hard to see." I had never had this happen before. I ignored him as I was BUSY at the time but had to hold back from popping the guy in the mouth. After I had bought the globe, the other bidder came up to me and was very pissed off at me and said some un-kind words. I just smiled and headed for my car. The two of them followed me out to my car!! I guess the reason I wasn't too worried about the situation was because the younger of the two looked to be at least 70 years old!!
I hope you are reading this pops. My globe looks GREAT lit up on my shelf!!!!
