A large fully signed and dated canvas of 1674 by Hambach was with Rafael Valls in 2005. It is thanks to this that we are able to fully attribute the painting as a work by Hambach.
Previously attributed to Vicente Victoria by Pérez Sánchez, it was Peter Cherry and Bill Jordan who questioned the attribution of a number of trompe l'oeils to Victoria and instead pointed to their Dutch origins, especially Biltius. The two heavily trimmed paintings in the Duke of Osuna's collection and previousy attributed to Victoria by Pérez Sánchez are almost certainly by Biltius.
