Canvas, maslo.70 - 105 cm
On the back of the canvas inscription; Kalyagin
Established, in my opinion ,1930-70 years.
In Soviet times, the picture was in Leningrad, in a fairly decent collection.
On the canvas, an incredibly thick coat of paint, the work was transferred to four and this had to pull it into a new, complex podramnik.Edinstvenny found my artist Kalyagin, nothing to do with this work imeet.Spasibo not if someone else, something tells.
