Concert of artists of the Mari Philharmonic at the forefront. Unfortunately, we do not know all the members of the front-line brigade. On the left in the photo is Vera Smirnova, People's Artist of the MASSR, the first Mari professional singer, in the background the artist's face is hidden, but judging by the hairstyle, the head of the front brigade Pavel Petrovich Toydemar (Stekolshchikov) is playing the bagpipes.
