Jackson Pollock watch - Untitled, 1950

Abstract expressionism is an artistic movement that emerged in the United States in the 1940s. It is characterized by the use of abstract geometric forms and bright colors to express emotions and ideas rather than realistic forms. Artists of abstract expressionism often used free brush techniques and layers of paint to create intense and expressive works. The most famous artists of this movement are Jackson Pollock, Mark Rothko, and Willem de Kooning. In addition to abstract geometric forms and bright colors, abstract expressionism is also characterized by the use of textures and rhythms to create a sense of movement in the work. Artists often worked on large canvases, using projection and dripping methods to create works with a great deal of energy and freedom of expression. The movement also had a significant influence on other forms of art such as sculpture, photography, and graphic arts. Abstract expressionism was also an international movement, with important artists in Europe and Latin America, although it is mainly associated with the United States. Finally, it is an artistic movement that marked the history of art by its freedom of expression, personal approach and search for emotion through abstract form. It also had an impact on architecture, interior design and fashion.
