The plaquette is decorated with the Virgin and Child, crowned by angels. For a simpler version of the same composition, see No. 141. Another variant is in the Museo Nazionale del Bargello, Florence.(1) The form is taken from a composition by Antonio Rossellino; the stepped edge suggests that it was meant to be framed. This coarse aftercast is from the nineteenth century.
