I ask the Board of experienced colleagues

[John Preston]

Friends,
Here are offering this kind of work is quite well-known Swiss artist Herman Ryudisyuli (Traugott Hermann Rudisuhli, 1865-1945).
They tell me that this oil on cardboard .
Works by this artist reproduced even at the pre-revolutionary home postcards.
Just afraid that this is not a reproduction was oleograph or something like that.
Heel should be dark , but here is something bright ...
And the nature of the loss is very suspicious.
Gallery, where I want to buy a job, refuses to be removed from the frame , because, supposedly , they sell on commission, and their rules can not violate the integrity of the work.
I'll be glad to hear your opinions.
