Three Diplomacy boards like this were made: one was auctioned at Origins, one was auctioned at GenCon, and the last is owned by the TD of GenCon's Diplomacy Tournament. Each power is made from a different type of wood. The game board also separates from the "legs" below. The board is "saved" for the Championship Round of the Diplomacy tournament on Saturday night.
Aside from Ian Cooper's perfect board, this is my favorite Diplomacy set.
