I got an email from Douglas Kent of Diplomacy World fame, so I thought I'd spread the word on various forums. Mr. Calhamer's estate is being liquidated. Among the items being sold on ebay is a first edition of Diplomacy, marked 1 of 500. In other words, Alan Calhamer's PERSONAL copy, which just also happens to be the FIRST COPY of Diplomacy published. EVER.
I am not particularly into collecting things, but for this I may make an exception. If I had to explain it to a non-Dipper, I'd say this was the equivalent, for an American, of being able to purchase Thomas Jefferson's personal copy of the Declaration of Independence, signed by all of the Founding Fathers.
