As well as working closely with Albert on several decorative schemes for the royal residences, Grüner was also a printmaker and specialist in the reproduction of Raphael’s works. This view of the Raphael loggia in the Vatican was published in Grüner’s Fresco decorations and stuccoes of churches & palaces in Italy during the fifteenth and sixteenth centuries (1844), which he dedicated to Prince Albert and the members of the Royal Commission on the Fine Arts. Albert incorporated this chromolithograph in his Raphael Collection.
