What is generally referred to as the first Cubist picture ?
The dominant understanding for over five decades , espoused most notably by Alfred Barr , the first director of the Museum of Modern Art in New York City and organizer of major career retrospectives for the artist , has been that it can be interpreted as evidence of a transitional period in Picasso 's art , an effort to connect his earlier work to Cubism , the style he would help invent and develop over the next five or six years .
