Casas did a portrait of a young Picasso, when he was 19 years old, in Paris, when both of them visited the Universal Exposition of 1900. In the background of this portrait we can recognise Paris, through some of its emblematic monuments, as for example the Sacré-Coeur or the blades of the Moulin de la Galette.An emblematic figure from the first Catalan Modernism, Ramon Casas leads, alongside other artists, the renovation movement of the Catalan figurative arts from the end of the 19th century and the beginning of the 20th century. His excellent artistic qualities are highlighted in this drawing of the famous portrait gallery given by the author to the Board of Museums in 1909, in which he fixed the image of the major personalities (artists, musicians and politicians) from the society of the time. This work has been selected for the project 'Partage Plus - Digitising and Enabling Art Nouveau for Europeana'
