I try to collect one nice cover from every country in the world, and I need YOUR HELP! Below you can browse through my collection, if you see your country is missing (or you can send me a better cover than the one I already have), please contact me :)
I prefer covers with WWF stamps, because this is my main (topical) collection. I also collect other WWF items, like local FDC / MC etc.
Thanks to my friend Wei Yi for this very nice cover picturing different pet animals!
Inside the envelope there was also this very nice postcard with lighthouse stamp and special postmark:
