EXHIBITION Paris, Mus‚e de l'Orangerie, Les Chefs-d'oeuvre des Collections fran‡aises retrouv‚s en Allemagne par la Commission de R‚cup‚ration artistique et les Services alli‚s, 1946, no. 200, description by C. Dreyfus. NOTES The basic form of this biberon is reminiscent of a design for a silver dish and cover by Giulio Romano (1492-1546) now in the collection of Christ Church, Oxford (illus. in Y. Hackenbroch, 'Reinhold Vasters, Goldsmith', Metropolitan Museum Journal, Vol. 19-20, 1984-5, p. 216, fig. 105). The grotesque mask forming the cover in the drawing was also possibly the inspiration for the covers of a number of ewers thought to be designed by Vasters (see Y. Hackenbroch, op.cit., pp. 213 and 216, figs. 104 and 106).
