I recently purchased a Durkin Megaphone Whiskey Bottle at an estate sale in Washington State. There are two types of megaphones that I have seen; one that has the octagon "panel" bottom and one with the straight bottom. Mine has the straight bottom. I have had very little luck finding what the resale value could be on it. It seems to be a pretty rare bottle and I have found some info on the internet but not much. Does anyone have more info?? Thank You!!
