While going through an assortment, I found this card for a joint issue between Germany ans Spain from 2003. Can any of our German experts tell me what this card is? Thank you.
Not sure about the card, but I do know about Czeslaw Slania.
He was a very famous stamp engraver known for his beautiful work. I can't remember who or where I heard about him, but it was someone who specifically collected his stamps.
I started to - but have since forgotten to put his stamps aside (it would make a nice sub-topic for collecting). But when I occasionally marvel at a particularly beautiful stamp I am not surprised to see his name in the stamp's inscription.
