1911 FIRST U.K. AERIAL POST LONDON POSTCARD IN OLIVE-GREEN TO LONDON WITH 'P. C. BURTON AND CO., LTD' ADVERTISING ADVERT. Fine London postcard in olive-green to Gracechurch St. London with KGV 1/2d Downey tied good large part strike 'FIRST UNITED KINGDOM/AERIAL POST/LONDON' date stamp SP 9 1911 Die unclear. On reverse RARE ' P.C. BURTON AND CO., LTD' advert 'Dear Sirs, This appointment is proof of our maxim: to be always 'in front'! If this is the only message you receive by the first United Kingdom Aerial Post, you will no doubt study it, front and back, more than an ordinary advertising post card. In fact, you will probably keep it, which we hope will prove that like all good advertising, the out-lay is merely an 'investment'. First example we can recall seeing. (Ref 141301)
