The price is for two works, this and this one https://artnow.ru/en/gallery/2/23714/picture/0/1026339.html
The sketch was made on the Arbat, near the Smolenskaya metro station, in 2001. It was already getting dark, the lanterns lit up. On the left is an artist painting a portrait of a girl sitting in an armchair in front of him; her friends are standing nearby. The figure of the guitarist is guessed behind the girl.
