The very scarce WWII Commemorative Cover for the 75th anniversary of the scuttling of the pocket battle ship Graf Spee. Captain Hans Langsdorff scuttled the ship in full view of 20,000 onlookers before he shot and killed himself. The cover bears two submarine stamps with B.F.P.O Battle of the River Plate postmark postmark dated 13 Dec. 14 and also the scarce Royal Crown and Lion postmark, dated 17 Dec 2014 on the anniversary date. It is understood that only 60 of this scarce cover exists.
