Is this Stalin's daughter? According to Grabar's Wikipedia entry, "...it was the 1933 Portrait of Svetlana that gave him an enormous and unwanted exposure at home and abroad. Grabar himself rated this portrait, painted in one day, among its (sic) best. The public identified its title subject as none other than Stalin's daughter (born in 1926, she could not have been Grabar's subject; the legend persisted into 1960s).
