Leon Wyczółkowski in the context of Young Poland

The looting of Polish cultural artifacts and industrial infrastructure during World War II was carried out by Nazi Germany and the Soviet Union simultaneously after the invasion of Poland of 1939. A significant portion of Poland's cultural heritage, estimated at half a million art objects, was plundered by the occupying powers. Catalogued pieces are still occasionally recovered elsewhere in the world and returned to Poland.

Priceless items of art still considered missing or found in other museums include works by Bernardo Bellotto, Anna Bilińska-Bohdanowicz, Józef Brandt, Lucas Cranach the Elder, Lucas Cranach the Younger, Albrecht Dürer, Anthony van Dyck, Hans Holbein the Younger, Jacob Jordaens, Frans Luycx, Jacek Malczewski, Raphael, Rembrandt van Rijn, Peter Paul Rubens, Henryk Siemiradzki, Veit Stoss, Alfred Wierusz-Kowalski, Leon Wyczółkowski, Jan Matejko, Henri Gervex, Ludwig Buchhorn, Józef Simmler, Henri-Pierre Danloux, Jan Miense Molenaer and many others.

Wojciech Gerson (Polish: [ˈvɔjt͡ɕɛɣ ˈɡɛrsɔn]; 1 July 1831 – 25 February 1901) was a Polish painter, educator, architect and art critic who was one of the foremost representatives of the Polish school of Realism during the foreign Partitions of Poland. He served as long-time professor of the School of Fine Arts in Warsaw, and taught future luminaries of Polish neo-romanticism including Józef Chełmoński, Leon Wyczółkowski, Władysław Podkowiński, Józef Pankiewicz and Anna Bilińska-Bohdanowiczowa among others. He also wrote art-reviews and published a book of anatomy for the artists. A large number of his paintings were stolen by Nazi Germany in World War II, and never recovered.

Croquet (UK: /ˈkroʊkeɪ, -ki/ or US: /kroʊˈkeɪ/) is a sport which involves hitting wooden, plastic, or composite balls with a mallet through hoops (often called "wickets" in the United States) embedded in a grass playing court.

The sport was codified in England in the 1860s and then spread overseas. However, similar games have been recorded back to the late Middle Ages. Today, there are several variations of the game.
