ADEN 1 1/2a blue postcard addressed to Berlin cancelled by large ADEN CAMP squared circle for MY 5 93. This cancel had a very short working life of just 19 months (3rd May 1893 to 31st December 1894) thought to be the second earliest known usage of this cancel. This came from the May 2021 Stanley Gibbons India and Area Signature Sale.
