Description
Air Post Exhibition (APEX) London 12th May (6th day) 1934 cover
On the 6th and final day of the exhibition, this cover was posted from the exhibition Post Office to the premises of stamp dealer R. Roberts of 430, The Strand, London. It bears a 1½d definitive cancelled by the winged cds, together with the final coloured commemorative cachet. Noticeable that it does not bear a commemorative adhesive label, had they run out of these late on the last day?
