Postcards with cute baby seal from Germany

I received both postcards from Germany, but from different postcrossers. I like the stamp of WWF on the first postcard very much, but I don't know, who and why put it on the postcard, as it is not WWF's postcard. On the second postcard I found sticker from 4th International Postcrossing Meet-up in Bielefeld in Germany. There was no message on this postcard, just signatures of about 45 postcrossers from around the world :) It was a big and nice surprise.

Cute Seals from second hand collection from Netherlands

This cute antarctic fur seals from South Georgia Island (second dark one you cand find hidden behid the light one)  have been sent to me by Marlies from Netharlands thanks to choose animal postcards tag on postcrossing forum. This is an older postcard from a second hand collection and has a little hole from a pushpin, but it is still amazing.
