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.
Ukraine and Russia
Thank you very much Volodymyr for these wonderful covers, esp. the registered Russian cover with no less than 6 WWF stamps picturing the wolverine (Gulo gulo)!
