1891 QV ½D BROWN POST CARD USED LOCALLY IN HAMPSTEAD, LONDON BUT MISSENT TO THE USA. Fine QV ½d brown post card used locally in Hampstead but evidently missorted and sent in error to the USA, apparently the card was received at Yale University library on June 6th and found in a periodical. The card was then returned with addition of a USA 2c issue cancelled 'NEW HAVEN.CONN/1' duplexes JN 8 1891. On front of card pencil manuscript 'Missent USA'. Most unusual. (Ref 128936).
