Since its creation in 1993, the CGAC has been exerting a rigorous effort into incorporating a series of representative pieces from the nineteen-sixties and nineteen-seventies to the holdings at the museum. As a result of the efforts of those whom, with their dedication, have contributed to the growth and maturity of the centre's collection, a better understanding is gained upon the incidence of artistic currents and styles that emerged during the mid twentieth century, on the conformation of visual arts.
The Human Stain embraces one of such movements—conceptual art—which without a doubt, has contributed the most into revolutionising contemporary cultural practices and yet it is not acknowledged and valued as it should be by certain sectors of the public. Through a broad selection of pieces from within the CAC's collections, the exhibition's curator, Ellen Blumenstein, suggests an in-depth approach to the work of imposing figures of conceptual ait, which marked an era in the art world during the late seventies, and to the works of up-and-coming artists whom adopted conceptual propositions and carried them on into new aesthetic territories.
