On Friday afternoon I went to the gallery and while I was visiting the second floor, I met two persons, an old man, probably a private collector, and a young woman, expert on art probably working for him, who were talking about the works in the gallery.
When I was close enough, I heard that the woman was explaining to the men what the artist wanted to express with the work they was looking and also the valuation; moreover, she was trying to convince him to buy the work saying "Oh, this is a very original work" or "I think that this is unique of its kind" and also "This will certainly gain in value in the future".
