Card addressed to Mrs M Beech in London, signed by Rear-Admiral Mark Kerr, one of the aviators on the Handley Page trans-Atlantic attempt. 'The machine left Harbour Grace [Newfoundland, Canada] on June 15, but developed engine trouble and the flight was abandoned early in July. The oval cachet is rare, being applied to only a portion of the mail.'
