-Please, help identify the artist
 

Good afternoon.
Please help identify the authorship, I can not read the signature.
and, if possible, to express opinions about the cost of painting

Josef DEDERICHS (1873-1948/58)

in my eyes, the artist is weak.

Your work is written not from nature, so many gross errors in positioning.

For the price, for instance, one similar work, size 70 x 91,5 cm, was sold in Germany in 2009 for 250 euros.

Ie
almost at the price of the frame.

Thank you very much for your comprehensive answer
