Catalogue of the exhibition 'La medalla modernista' which shows how at the end of the nineteenth and the beginning of the twentieth century, all over Europe there was a re-evaluation of the medal as an 'objet d'art', at a time of intense renovation in aesthetic trends. This splendid period for the medal must be seen in the light of the incorporation of sculptors to this art, the application of new machines in the system of production and society's interest in using the medal as an ideal means for the expression and dissemination of modernity.
