Praca odbiegająca od innych tego malarza. Nigdy bym nie zgadł, że to Henryk Gotlib. Może z początkowego okresu? Niezła martwa natura.

May I ask what makes you think this may not be by Gotlib?
I,too, am a little doubtful and there is no clear Provence for the work.
I am not familiar with the entire oeuvre of Henryk Gotlib. Therefore, I am not in a position to judge whether this particular painting had been painted by him or hadn’t. However, it is definitely different from those that I’ve seen so far that was created by his hand. So, being quite doubtful I expressed, in few words, my private opinion. Also, I encouraged other who may consider buying this painting to educate itself and make own decision based on learning on Gotlib’s possible change of brush strokes style over the years. Bottom-line, one should make its decision based on own knowledge, not seller’s statement/opinion.
