Hello! 'll Show the real value of the picture, please. Inherited from his great-grandfather, insisted that Aivazovsky, which is written on baguette. But the signature on the work itself, someone erased. Wore it in the Magnum ARS, they just specialize in AYVAZOVSKOE, said it was not him, but painting an old, bad, etc. Maybe a student wrote, I do not know, in general, help to understand, I want to sell it, circumstances are forcing the issue on what you can expect. The size of 25x35 cm, made of glazed tiles, no no signatures on the back, tlko on baguette.
