Frogs and toads, fairy tales and fantasies from illustrators

Last offered at auction at Parke-Bernet in New York in 1945, as part of the famed Bronson Winthrop collection, a drawing made by John Tenniel for Alice through the Looking-Glass made $16,000 (£12,600) at Sotheby’s New York (25/20/12.5% buyer’s premium) on June 13 – though the saleroom had hoped it might make twice that sum.
