Expertise: Sonia and Robert Delaunay
Spain.
Richard Riss lives in Spain and is the holder of the Sonia Delaunay (1885-1979) and Robert Delaunay (1885-1941) archives. Jean Louis Delaunay, Sonia and Robert’s grandson, appointed Riss as the expert to authenticate his grandparent’s paintings. Riss authenticates the Delauney paintings; the grandson signs the certificates. Riss is currently finishing the catalogue raisonnes for both artists. |
