beads of Leonardo's Lady with an Ermine. Attribution It is attributed to Leonardo by art historian Peter Hohenstatt (University of Parma). Art historian David Bershad (University of Calgary), who participated with Hohenstatt in an examination of the portrait in May 2010, later said "there's not enough evidence to sustain an attribution", describing the painting's style as unlike any work by Leonardo.
