Painting imitators Aivazovsky. Help evaluate and determine the author

[Sveta]

Previously, I have such information on this painting (information provided by the deputy. Head. The department of painting the second half of the nineteenth - early twentieth century, Tretyakov Gallery):

Perhaps this picture imitators Aivazovsky. It works by an unknown artist of the late nineteenth - early twentieth century. The signature on the painting can be read as AK (?) - One thousand nine hundred and sixth year. In practice, the expert met the work of artist A. Karzhakina (or A. Karzhavin; signature is not clearly legible) - Sailing ship in the stormy sea, imitators IKAivazovsky. Judging from photos on the plot and some stylistic grounds it is close landscape of the unknown, not in the references to artists, A. Karzhakina (Karzhavin?), The master of the middling sort. Size: eighty-cm per meter. Signed in the lower right corner - in 1906

So I ask you to help with the definition of the author and the approximate cost of the painting. Where it is possible to offer for sale?
Thank you in advance.
