The Notebooks of Leonardo Da Vinci — Complete by da Vinci Leonardo

3. A study in red chalk for the bust of the Infant Christ--No. 3 in

the Windsor collection (Pl. XLIV). The well-known silver-point drawing on pale green paper, in the Louvre, of a boy's head (No. 363 in REISET, _Notice des dessins, Ecoles d'Italie_) seems to me to be a slightly altered copy, either from the original picture or from this red chalk study.
