Perhaps living in the desert makes one appreciate ice. In Phoenix, Arizona, Michael and Cecilia Ball proclaim that they are: "Arctic and Antarctic Specialists...Stamps, Postal History, Expeditions, Town Cancels, Local Posts, Cinderellas, Coins, Postcards, Ephemera, Books & More from the Polar & Sub-Polar Regions."
Their Webstite doesn't have a catalog up yet. It reads like a mom-and-pop restaurant. Send a list of what you want and they'll see what they can do.
They look like nice folk.
