My Babcia brought this on one of her trips to America to visit us when she was younger. It is a collection of the Kings of Poland.
I always loved looking through it but was always told I wasn't allowed to touch it.
The price was 450 zloty. Because I am not sure exactly what year this was from, I cannot tell you how much that cost in US Dollars at the time.
This is a description page of the collection of cards. There is a list of the kings up until Stanislaw Poniatowski.
And here is the card of the first King of Poland, Lech I.
The text below his picture reads: "Lech I. Family name of Slowianczyk (sort of like a Dynasty), first King of Poland, The city of Gniezno from a nest of an eagle that he found he created [the city]; Lived around the Year 550. Christian Era._" Poland was not at that time Christian, however, the years mentioned are from the Christian calendar.
Here is a link to a beautifully written version of the legend of Lech and Gziezno.
And here is another about the Legend of the Polish Eagle. The red fields they talk about I have seen for myself and they are a beautiful color.
This video is a favorite of mine. In the very beginning, you see an eagle flying and then a man stab his spear into the ground and a town grows from nowhere. That is Lech and Gziezno. The video is worth watching all the way through.
