A letter from the artist director of the Prado, Madrid, Jose Villegas, dated April 24, 1913, in the artist’s papers, gives the artist permission to copy this picture from May 10.
In her autobiography Faith is a Song (p. 240), Jessica Dragonette, in describing her first visit to the artist’s studio in 1940, says, ‘On the walls were several copies of paintings by Velasquez: Don Carlos on horseback and the artist painting the infanta. Muller-Ury had copied the pictures in Spain and kept them as technical reference.’
