Cuba- Partridge Pigeon & Antillean Hummingbird

To commemorate the World Festival of Endemic Birds in Cuba 2012,a pictorial postmark of a Partridge pigeon ( Starnoenas cyanocephala ) was used to cancel an 2011 Antillean crested hummingbird 

(Orthorhyncus cristatus)

12-12-12. A unique date

A date to remember when philatelists all around the world exchanged covers  to receive the unique postmark. For local mail I always request the use of definitive stamps and you can see here three of the values from the 2005 set which are still in use today.
