 Sometimes he omitted the enamel on the face and hands of his figures, especially in those cases where he had treated the heads in a realistic manner; as, for example, in the tympanum relief of the meeting of St Domenic and St Francis in the loggia of the Florentine hospital of San Paolo, a design suggested by a fresco of Fra Angelico's in the cloister of St Mark's.One of the most remarkable works by Andrea is the series of medallions with reliefs of the Infant Jesus in white on a blue ground set on the front of the foundling hospital in Florence.These child-figures are modelled with skill and variety, no two being alike.
