The Greeks did it. Rodin did it. All sculptors made hair out of clay. This particular piece is by Amadeo Modigliani (1884-1920), who signed it and pointed out that in the rear of the sculpture, there was limestone. It is 25 1/4 inches high and was made c. 1910. The lady is even wearing a tiara to hold back her hair, parted in the middle. In Christie’s “Art Impressionniste et Moderne” sale this June in Paris, its estimated value is $4,935,457 – $7,403,185.
