What to do with counterfeiting

[Vladimir]

Well, it says all the most honest:

The picture of Vladimir Fedorovich Stozharov "Yaroslav's Court" (authorship presumably by signature), oil on canvas, 40x50 cm, 1965. The son finds this work a fake, but it is a subjective opinion, and therefore now be given to an independent examination.
This is a preliminary sketch or small version of a larger and later (1972) pictures VF Stozharov Novgorod. Yaroslav Court.

SergeiSK information is not concealed, on the contrary warns the potential buyer.
