An image of one of the first domestic aircraft was decorated with a transformer box on the square of Lev Matzievich. Graffiti with the "Ilya Muromets" - the bomber, which in 1914 was designed by Igor Sikorsky, - appeared in the framework of the youth eco-marathon "Clean Tomorrow".
The creation of the drawing was timed to the birthday - May 13 - one of the first domestic aviators Lev Matsievich.
