This is one of my favorite pieces I have had the pleasure of owning. Everybody knows Christy Mathewson was exposed to mustard gas while stationed in France in WW1 which eventually took his life. This is one of Mathewson's Official Military Orders that essentially served as Matty's ticket home from the war. This letter informs Mathewson that his services are no longer required in France and that he will be returned to the United States.
