USA registered return receipt cover for package signed for by Major George Herbert Scott, commander of the English R34, R100, and ultimately the ill-fated R101 whose crash took his life. Very rare, and with a great provenance: from the estate of the original collector, John Strauss, who collected these (and everything else Zeppelin) in the period as new issues / first flights. The clever collector sent a registered package to Scott's residence in Cardington, return receipt requested, so that the autograph was returned. With the collector's original typed explanation, completed before Major Scott's fatal flight the next year.
