Jan Matejko is a famous 19th century artist who was born in Krakow. He is best know for his oil canvases documenting famous 19th century Polish battles and persons of interest, like kings and politicians.
I thought this a rather clever piece. Situated in Krakow's Planty Park -- a circular 4 km long park that used to be the city's moat -- it shows the artist sitting in front of a large picture frame. There is no canvas and what you see framed is pleasing scene of the old wall and vegetation of the park itself. It was fall when we visited, so the colors stood out beautifully.
