With the growth of overseas airmail in 1928–29, the Chilean Post Office recognised the need for postage stamps specifically for the purpose of prepaying the airmail rate. As no international airmail stamps were available at the time, a provisional issue was created to meet demand. We discuss the production, known varieties and postal usage of the 1928 airmail overprints.
The rapid expansion of overseas airmail due to the efforts of Air France and Pan American-Grace Airways in 1928–29 created the need for postage stamps specifically for the purpose of prepaying airmail. The stamps issued in 1928 were provisional issues since no international airmail issues had yet been produced.
The Presidents and Famous People series of stamps, with and without watermark, were utilised and the first overprints were made on adhesive stamps reading ‘Chile Correos’ in the legend. Later, between 1928 and 1934, overprints were made on adhesives where the legend read ‘Correos de Chile’.
