Outside of Rynek Glowny (the main square in Krakow), is this fantastic display of paintings for sale. Each day they are set up on this wall (which extends rather far). Krakow is a hidden treasure for new and old art alike. In fact, inside the Czartoryskich Museum less than a mile from here holds Leonardo da Vinci's, "Lady with an Ermine," which was breathtaking to see, especially in a city as beautiful as this one.
