Dear Sylvain, I like your blog entries very much. What is also interesting to notice on the photo oz the trumpet playes is the street art stencil of “Superoperater” who is a funny character from the movie “Kako je propao rokenrol” and was played by Serbian conceptual artist Kosta Bunusevac. I think it was done by TKV who is the best Serbian street artist ever. You should check her work both online and on the streets and walls of Belgrade
