Galeria Joan Gaspar-Barcelona, has since 1992 been continuing this tradition, while it also presents young artists whose reputation has become consolidated over the years, such as Enrique Brinkmann, Claudi Casanovas, Igor Mitoraj, Etienne Krähenbühl, Jean-Baptiste Huynh, Concha Sampol.
Recently, artists as Gaston Louis Roux and Suzanne Roger from the Paris School (1900 - 1950) not very well known in Spain, are as well present in the Gallery.
