 Messages change throughout the year, and include seasonal messages ("Merry Christmas / Joyeux Noel") and promotional messages (such as Canada Post's web address).Other post offices such as the Isle of Man Philatelic Bureau also create special pictorial cancellations as they did in 1985 to mark the anniversary of the aircraft Douglas DC-3.A special handstamp was created  depicting a Dakota flying "free" and not "boxed in".
