The research and doctorate studies of the experts help us to document and trace the provenance of some works. We know that this painting by Ignasi Maillol belonged to two large and important collections before becoming the property of Crèdit Andorrà: the Plandiura collection and the Rivière collection. We can know this thanks to the back of a photograph preserved in the Francesc Serra Dimas fund – Barcelona Photographic Archive – where it is specified “Lluís Plandiura collection – no. 582 of his catalogue”. In the Rivière collection, no. 250 of his catalog where he arrived in 1948.
