To me in particular, lists are hateful. All selection is personal. Guernica and The Birth of Venus should not have been there for me. And the number one painting must have been Gustav Klimt's Kiss. I find the story behind this work extraordinary, including the materials it is made of. It is said to have gold flakes and dust. No wonder when they put it up for auction, even if it wasn't finished, they immediately bought it. If we look at the dimensions, we realize that it is large, compared to, for example, The Persistence of Memory, which measures only 24 x 33 cm. An insignificance in comparison with the work of Klimt. I would like to see the end of that list!
