5) Pierre-Auguste Renoir – Bal au Moulin de la Galette, Montmarte
Painted in 1876, it was sold by owner Betsey Whitney through Sotheby’s, New York, in 1990. The high bid came from a Japanese businessman named Ryoei Saito, who paid $78.1 million back then. This translates to $122.8 million today. It is important to point out that two versions of this painting exist. The first one is housed at the Musée d’Orsay in Paris, while the second, smaller one, is the one that Saito purchased. In addition to this masterpiece, Saito also purchased a famous Van Gough work as well (see number 4 below).
