Description
1919 (Jul 12) Martinsyde “Supplementary Mail” envelope franked Alcock & Brown $1 on 15c, correctly dated 12 July 1919, sent to Sopwith Aviation Co. in London by Captain Raynham with enclosed letter signed by him, missing most of backflap. The flight crashed on take-off, and Capt. Raynham subsequently went to England by ship, forgetting to turn the mail over to the Post Office until January 7, 1920. An important airmail rarity as only 25 covers were added to the mailing on July 12th; ex Bute.
