Portrait of lady - Ambrogio de Predis

It early 1900s thought to be Lucrezia Crivelli's portrait (A. Edith Hewett. A Newly Discovered Portrait by Ambrogio de Predis // The Burlington Magazine for Connoisseurs, Vol. 10, No. 47 (Feb., 1907), pp. 308-313 [1]The Burlington Magazine for Connoisseurs)

It is likely that this portrait is also a Milanese work. The Moor's head and the letters 'L' and 'O' which ornament the buckle of the belt may allude to Lodovico il Moro, Duke of Milan.
