What has been the significance of sport for the European avant-garde in the first half of the 20th century? From an international and interdisciplinary perspective we show the extent to which avant-garde art and culture was shaped by the dynamic encounter with modern sports. Our focus lies on avant-garde artists, groups, movements and institutions across Europe (including Cubism, Futurism, Vorticism, Purism, Expressionism, Dada, the Bauhaus, Constructivism in Central and Eastern Europe), thereby unfolding the diversity of avant-garde responses to modern sports. The book in front of you includes fascinating readings in the fields of aesthetics, visual cultures, cultural history and politics and highlights why specific kinds of sport such as cycling, boxing and football became important for avant-garde movements and artists.

The art market today is like a Monopoly game. There is an underworld of art secrets unknown to the public and many art experts around the world. This art collection was hidden away by the famous artist Picasso and his wife Jacqueline Picasso to keep them away from the hands of his illegitimate children, who today are in charge of the authentication certificates for the artist Picasso's artwork. This art collection is unique and has never been seen by anyone in the art world. Now, in this book, I am giving you the chance to see these unseen artworks, along with some amazing oil paintings by some of the other top artists in the world. Most of our Picasso paintings have been authenticated by Picasso himself or his wife Jacqueline. Some authentication was done in the artist's Barcelona museum, opened in Spain in 1963; others were authenticated on 18 February 1980 and 20 April 1982 by Jacqueline, with the help of Jon Miro and others. This is the story of one painting that will change history and show the facts, and what is known about Picasso's artwork, to the art world. This is a one-of-a-kind art discovery that will be registered in history as one of the biggest art discoveries made by one person. It will prove that this artwork, along with more than a hundred oil paintings and other artworks, was part of the private collection of Picasso himself and his wife Jacqueline.
