AlP P05T By Douglas B. Armstrong Newfoundland's New Air StampsNewfoundland is on the point of issuing two particular postage stamps for use on aerial correspondence, one ofwhich, 10 cents green and black, will depict an aeroplane over the Narrows at the entrance to the harbour of St.. John's,whilst tbe other, 15 cents blue and brown, shows the Vickers- Vimy aeroplane at Quidi Vidi waiting for the first trans-atlantic flight in 1919. They will be used chiefly on letters to Labrador and the northern Settlements. The first design is one of a series of three essays for air-mail stamps prepared in the summer of 1919, when the inauguration of a regular air post to Halifax, N.S., wasmooted. The other two represented an aeroplane in flight and the head of a caribou. Latest from ColombiaThe semi-official air-post service maintained by the Sociedad Colombo-Alemana de Transportes Aereos, under contractwith the Republic of Columbia, is a model of efficiency, and is very largely patronised by the business community.By the use of this service a saving of several days is effected in transmission of correspondence from the coast to theinterior. Supplementary charges on air-post letters, etc., are defrayed by special stamps issued by the company, inaddition to the normal postage which is paid in ordinary Columbian postage stamps. A new series of stamps for theS.C.A.D.T.A. has just been printed at the State Printing Office, Berlin, differing from previous issues in that thedesign represents a hydroplane in flight instead of an aero- plane as heretofore, and the inscription reads, " Servicio deTransports Aereos en Colombia " instead of " Servicio Postal Aereo de Colombia." The colours of certain denominationshave also undergone a change. The aero stamp collection affords an example par excellenceof the modern postal and historical school of Philately, which is as far removed from the popular conception of a schoolboy'sstamp album as is a gallery of old masters from a collection of cigarette cards. The philatelist of today is a student, notonly of stamps, but of postal history, treating his stamps as symbols of the system that gave them birth. In this way,by means of liberal annotation and extra-illustration the modern stamp collection becomes in effect a documentaryrecord of postal progress. This method of collecting is especially applicable to air stamps and the majority of aero-philatelists favour the " Graingerised " or extra-illustrated collection as calculated to enhance both the interest and valueof their philatelic treasures. Air stamps provide even greater possibilities in the way of documentary embellishment thanperhaps any other phase of stamp collecting, since the air stamp collection embraces of necessity many items that are barredfrom the pages of the everyday stamp album, such as special cancellations, quasi-official labels and even souvenir stickers. Of late there has been much controversy as to what may ormay not be legitimately included within the purview of aero- philately. Many enthusiasts favour insertion of portraits ofaviators with newspaper cuttings relating to the mail flights made by them, but it was certainly stretching a point when ata public stamp exhibition, one exhibitor showed with his stamps a portion of an aeroplane propeller ! After all " thestamp's the thing," and whilst a certain amount of annotation tends to enhance the attraction of an album page, overelaboration in this respect has the reverse effect by dwarfing the main feature of the exhibit. A nice sense of discrimina-tion is therefore a most necessary attribute to the successful arrangement of a collection of air post stamps. Readers are invited to forward to the Editor of FLIGHT letters, etc., bearing aerial stamps or postmarks for mention in this column, as well as out-of-the-way varieties, etc. We shall also be pleased to hear from correspondents interested in air-stamp collecting, and to answer any queries.
