For today, canceled May 12, 1937 at Vancouver, British Columbia, Canada:
May 12, 1937 was the date of the coronation of King George VI, as stated in the flag of the cancel. In addition, the underlying stamp is Scott 237 which was issued in honour of the coronation.
Seen here is an oxidized copy of the 1933 twelve-centavos airmail stamp. It should appear orange in color but oxidization has turned it brown. The illustration under the overprinted outline of an aeroplane, is of Pier 7 at Manila Bay.
The Stamp World online catalogue (SW.C) has assigned their number 357 to this stamp.
The reason for overprinting this issue was because of a sudden surge in the demand for airmail service and these overprints would help in the sorting of mail.
