The street in Skadarlija that I posted on January 11th also boasts several trompe l'oeil murals, including this one. In this mural you can see one of Belgrade's popular street figures, Žika Obretković, playing his flute. Žika, who is developmentally challenged, has been playing around the Skadarlija area for at least 15 years, where he entertains passers-by.
