Also in this exhibition was a painting titled Boulevard des Capucines, a painting of the boulevard done from the photographer Nadar's apartment at no. 35. Monet painted the subject twice and it is uncertain which of the two pictures, the one now in the Pushkin Museum in Moscow, or that at the Nelson-Atkins Museum of Art in Kansas City (shown here) was the painting that appeared in the groundbreaking 1874 exhibition, though more recently the Moscow picture has been favoured.[2][3]
