Lovely cover from Philippines

Thank you very much Myron for your help with my WWF collection! This is the nice cover I received today, indeed a very nice surprise! :)

The stamps picture:

• the Visayan Warty Pig (Sus cebifrons; http://www.ultimateungulate.com/Artiodactyla/Sus_cebifrons.html) and
  
• the Philippine Spotted Deer (Cervus alfredi; http://www.iucnredlist.org/details/4273) and were issued on July 15, 1997.

The envelope Myron used to send me the WWF item is very nice too. The four stamps on the cover were issued on 25/03/2009 and picture different Philippine minerals: Quartz, Rhodochrosite, Malachite and Nickel. Philippine Post also issued a souvenis sheet in this serie, showing four other minerals. (see: http://www.philippinestamps.net/RP2009-Minerals.htm#RP2009-Minerals)


Notice the cancellation on this envelope: Myron sent this cover on my birthday :)
