Baldessari worked with all possible mediums but, as this exhibition demonstrates, the most significant are those works "in between mediums", for example language and drawing. As a conceptual artist, his work challenges us to think about what we are seeing or what he wants to tell to us. The meaning we seek is, many times, associated with situations or sensations typical of Western culture. In the works where he throws the ball hundreds of times and is photographed in the different poses of those throws, he decides to intervene by sticking tape-lines in different colors. We can link this work with humor (those strange poses) although there is a neatly defined simplicity with the lines in yellow or red. 

In all the works there is humor and references but, above all, there is sarcasm.
