Indian Air Mail - The First Two Decades (1927-1946)

Auxiliary Markings are often considered secondary in importance as compared with the postal franking, cancellation and delivery date stamps on a cover. This exhibit shows this is not the case. Auxiliary markings are cryptic instructions that determine the route, postal rate and handling of postal articles. The entire story of the handling of a cover lies therein. One can thus argue that Auxiliary Markings are the most important indicator on a cover and deserve due recognition in postal history studies
