What is "hofamterspiel"

Hofämterspiel (Court-office Game), one of the earliest card games on record preserved in its entirety with all forty-eight cards intact, is a major 15th-century medieval handmade deck commissioned by Ladislaus the Posthumous, king of Hungary and Bohemia and Duke of Austria from 1453 to 1457. It was found among the great collection of art treasures of Archduke Ferdinand II of Tirol in castle Ambras, Austria, together with another called Ambraser Hofjagdspiel.
