[ Sir Alan J. Cobham, English aviation pioneer. ] Circular printed letter in the form of a facsimile of a signed letter by him, thanking the recipient for making 'our Air Display a success'.

Cobham started his National Aviation Day displays (known as "Cobham's Flying Circus") in 1932. These displays were a combination of barnstorming and joyriding by a team of skilled pilots in up to fourteen aircraft, ranging from single-seaters to modern airliners. The show toured the country, calling at hundreds of sites from regular airfields to fields cleared for the occasion. 1p., 4to. In good condition, lightly aged, worn and ruckled. Nicely printed in black over a halftone red map of Great Britain and Ireland. At head, also in red: '1932 - 1933 - 1934 -1954', and at foot: '"Make the Skyways Britain's Highways'. The letter reads: 'Dear Sir/ | Please accept my sincere thanks for all the help you have given to make our Air Display a success. | Without your kind collaboration & that of all the numerous friends we meet on our journey round the country, the work of conducting our Air Display campaign would not be possible | A thousand thanks | Yours very truly | Alan. J. Cobham.' Also included is a newspaper cutting of large photograph of 'Some of the many spectators at yesterday's Aviation Day display given by Sir Alan Cobham at Cambridge.'
