I think the seller is a bit optimistic. There are a handful of these floating around and as late as they are I don't see anyone paying 5K for one...but I could be wrong!
Kills me how folks waste their own and everybody else's time putting bottles like that on ebay. Coasttocoastantiques is another. Great bottles with almost zero chance of selling. Folks that spend that kind of bread know their bottles and you're rarely gonna slip one by on 'em. Compare that to the recent Indians Panacea (great bottle) which closed at $4,050.00. The starting bid? $0.01. A lot of fun to watch sales like that.
