Gershwin’s musical sketch book is a $100,000 hit in California

ONE notable item from the Bonhams & Butterfields sale of March 23 was a rare copy of Jacques Gautier d’Agoty’s colour printed Anatomie de la Tête of 1748 that made $19,000 (£10,220) – but not the top price lot, a Gershwin sketchbook that made $100,000, or indeed several other interesting items.
