The banner of Misericordia (Mercy) is a work of the Catalan architect Antoni Gaudí projected for the procession to the Sanctuary of Misericordia in Reus of the reusians residing in Barcelona as one of the acts for the 1900 Holy Year. It is known by the two front and back photographs published in the Semanario Católico de Reus (Reus Catholic Weekly magazine) in July of that year. It included another photograph of the procession in which Gaudí is seen as part of a large group of pilgrims and the banner being carried by one of them.
