A large mural called Supilinn 15 created for street art festival Stencibility by Polish artists Sepe and Chazme connects the cultures of Poland and Tartu. The mural is inspired by the works of two Polish artists born in Tartu in the beginning of the 20th century. One is the famous Spodek building created by architect Jerzy Hryniewiecki (among others) and the other is a well-known painting titled Autobus by painter Bronisław Linke that has become quite symbolic.
