FLIGHT, ApRit 11, 1929 AIR POST STAMPS By DOUGLAS ARMSTRONG(Editor of" The Stamp Collector") Retrospect AERIAL progress in 1928 is indicated by the fact that "no lessthan 115 new varieties of stamp for air postage were issued throughout the world, an increase of sixty upon the previousyear. A considerable proportion of these originated through the opening up of new air post lines in South and CentralAmerica, including the Transatlantic Latecoere service between Toulouse and Buenos Aires, whilst others marked thecourse of Lindbergh's Goodwill flight through Central America and the West Indies. Seldom has popular interest in airpost collecting been aroused to the same extent as by the special stamps issued by the German post office in connectionwith the Europe-America flight of the giant dirigible " Graf Zeppelin " in October last, with the consequence that lettersbearing these picturesque vignettes already fetch com- paratively high prices, notwithstanding the large numberscarried by this historic mail. "Wright " Aeroplane StampAir post collectors are not to lack for an appropriate souvenir of the Silver Jubilee of the aeroplane which wascelebrated in England and America on December 17, 1928. The United States government rose nobly to the occasionwith a pair of commemorative stamps, first issued at the International Civil Aeronautical Conference held in Washing-ton by invitation of President Coolidge on the 12th, 13th and 14th of that month, the 2 cents denomination of whichbears a picture of the original " Wright " aeroplane used for the first heavier-than-air flight at Kitty Hawk, N. Carolina,in 1903 and now preserved in the South Kensington Museum. The companion stamp, 5 cents blue, depicts a modern mono-plane in flight between the New World and the Old, thus contrasting the development of aviation in the past 25 years.For the trifling sum of 7 cents (U.S. currency), therefore, all who are interested in the rise of aerial power can possessthese fascinating relics of the jubilee of flight. South American IssuesFrom Chile comes news that owing to the suspension of the Santiago-Valparaiso air post service the aero stamps dis-tinguished by the imprint of a " Condor " were withdrawn from circulation at the beginning of September, 1928, afterhaving been in use for a little less than three months. This has always been a difficult set for collectors to obtain as onlyeight thousand are said to have been issued at all, exclusive of the two surcharged values which were withdrawn fromcirculation almost immediately and it is likely to prove a very sound investment, like several other recent South Americanseries that have unexpectedly passed into obsolesence. The Scadta Company of Colombia is gradually extending itsoperations to the neighbouring Latin American republics. Additional denominations of 40 and 80 centavos are reportedas having been included in the semi-official Colombian set as from October, 1928, and now we have the 20 c. grey and 30 c.blue overprinted "ECUADOR-PROVISIONAL 1 Sucre" and " 1 \ Sucre " respectively in connection with the servicelately inaugurated between Guayquil and Buenaventura. An experimental flight to Peru was successfully carried outand a further extension of the regular air post service may be looked for in that direction in the near future. An air mail service from Asuncion (Paraguay) to BuenosAires (Argentina) was due to commence operations in December, 1928, and special stamps foreshadowed in thisconnection. The present air post stamps of Uruguay are about to be replaced by a new issue in varied and morepicturesque designs. From Bolivia comes a striking set of three particular airpost stamps lithographed by the Imprensa Nacional with the badge of the Lloyd Aereo Boliviano (a subsidiary of theDeutsche Aero Lloyd) flanked by vignettes of native huts and palm trees on the one side and the Andes on the other.These are used to denote the supplementary air post fees payable to the operating concern comprising 15 centavosgreen, 20 c. blue and 35 c. carmine, of which the total printing amounted to 100,000, 150,000 and 300,000 respectively. Persian ProgressFollowing on the improvisation of certain high value Fiscal stamps for air post purposes pending the arrival of thelong promised new permanent series that is being printed in Holland, the lower values of the same series from 1 chahiup to 1 Kran, five in all, have been similarly distinguished and pressed into the service. Less than 5,000 sets are believed tohave been overprinted and it is understood that they are not on sale to the public in the ordinary course, but are affixedby the postal officials themselves to letters handed over the counter for transmission by air post.
