Portrait of the Grand Duke of Lithuania and the King of Poland Jogaila (1377-1381,1392/1386-1434, by the artist Michael Godlewski, 1863
This card was sent knowing that I tend to be a fan of Poland and Polish history. This is an image of Władysław II Jagiełło, first monarch of the Jagiellon Dynasty. Under his rule Poland-Lithuania was one of the largest countries in the world. He was also the supreme commander of the forces at the infamous Battle of Grunwald on July 15, 1410 which decimated the Teutonic Order of knights.
This card in particular appears to be for a July-October, 2012 exhibit in Vilnius called Portraits of the Rules and Magnates of the Grand Duchy of Lithuania from Museums in Ukraine. The painting depicted above is listed on the card as being held by the Lviv History Museum in Ukraine.
