Event cover

Event covers are a type of stamp covers (decorated, stamped and canceled commemorative envelopes) that are created to celebrate an event or note an anniversary.

It explains what is being commemorated on what date and generally also includes an illustration page.

Cancels can often be obtained in the city of the event (such as Kitty Hawk for the Wright Brothers first flight anniversary).

A good example of a special Event cover was one by the Isle of Man Philatelic Bureau that was issued in 1985 to mark the anniversary of the aircraft Douglas DC-3, which was of interest, not only because of the high volume of air mail handled by Dakotas at that time, but also the link between the names of Douglas, Isle of Man, and Dakota - Douglas DC3.

[1] A 26p stamp was specially issued by the Isle of Man and a special handstamp was also created for these covers,[2] which was deliberately created with a Dakota flying "free" and not boxed in.
