That chip might have very well been used at the Brown Hotel but it was probably used in many places in the teens and twenties. Try to prove it though. We call them generics. Rich Hanover might have an opinion on them. There is no first hand info on the chips as far as I know. I seems he got them from someone who's uncle knew someone that said they were from the Brown Hotel. I could sell a can of Coke with a letter of authenticity saying it came from the president's mini bar by the Oval Office in the White House. But.....so what?
