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.
Olympic cover from Slovakia
Thank you Robert for this very nice cover with Vancouver 2010 Olympic Games stamp picturing bobsleigh. Maybe I should consider to start a topical collection on Olympic Games too, I seem to like these stamps a lot. (see Macau post)
