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.
New WWF cover received from Brazil, thank you José Luiz for your help to return the WWF stamps on an envelope.
The WWF stamps picture muriquis (Brachyteles arachnoides).
