[6th Marquis of Donegall, as President of the Nation Federation of Jazz Organisations. On behalf of.] Autograph Signature to circular to the Kent County Army Cadet Force, offering tickets for the 1951 jazz concert at the Royal Festival Hall.

A nice piece of ephemera, associated with a landmark concert in the history of British popular music. 1p, 8vo. Twenty-three-line typed circular, with perforated order slip for tickets at end. In fair condition, lightly aged. Signed ‘Donegall’ and with autograph address to ‘Dear Mac Queen Pope’ (i.e. the theatre historian W. P. MacQueen Pope). The circular begins: ‘I am writing to you because H. R. H. Princess Elizabeth has graciously consented to attend the Concert to be held by the National Federation of Jazz Organizations, of which I am President, at the Royal Festival Hall, South Bank, on Saturday evening, July 14th. / This Concert would have been in any case a great landmark in British Jazz because it is no small honour to this type of Folk Music to be granted the use of the Royal Festival Hall. But it becomes historical due to Her Royal Highness’s intended presence - it is in fact to the best of my knowledge the first time that Royalty has publicly recognised this musical idiom.’ He offers boxes to the event ‘On behalf of my Kent Army Cadet Force Welfare’ (on the letterhead Donegall is listed as one of four members of the ‘Welfare Committee’). He concludes: ‘Such has been the nation-wide interest in the revival of genuine Jazz Music that I am sure you will not want to miss this unique and royally honoured presentation of the best that Britain has to contribute in this branch of Music.’
