Stretcher tree. No signatures or in corners or on the reverse side is not visible (can not tell), because now than then wiped after the war. All injuries received during the war from shell fragments. I know only that before the war she was in Strelna, the house his great-grandfather. At some point he got her information there.
Please help me determine the age and the author of the picture.

Good afternoon. Generally photo was taken in daylight without a flash (except the last photo). I just wrote that painting somebody than wiped clear for what purpose, and in itself is very dark. But I'll try something else to do.

Judging by the manner of the light reflections in the water and, especially, in the manner of writing of stones, it is, in my opinion, seems to work Artel Ducommun.
