The Hungarian language site of Talma Publishers has that they offer the award winning "A történelmi Magyarország atlasza és adattára 1914." (Atlas and gazetteer of historical Hungary 1914) for a discounted price until Christmas. They ship it for 3640 Hungarian Forints, instead of 5600. Whether this discount is good for foreign addresses, too, or not, I'm not sure. If interested, ask them.
