“Via Airmail to Exchange Office”
“A recent bulletin of the Post Office Department, signed by W. Irving Glover, Second Assistant Postmaster General, emphasizes that articles addressed for delivery in foreign countries which are to be dispatched by air mail in this country to a coast office for dispatch by steamer should be marked in the upper left-hand corner “By Air to Exchange Office”. (in the July 27, 1929 number of the “Weekly Philatelic Gossip” page 558).
This cancel was placed in case of underpaid postage for airmail from London or Paris in the post office of dispatch, sent to New York, where the airmail indication was cancelled by double parallel bars. (source: “Via Airmail” by the American Air Mail Society).
The usual color is violet, although there is a wide range of violet-shades.
