Many of the lots bore inscriptions, some of them illustrated - albeit these were not contemporary - and the 1957 first of How the Grinch Stole Christmas seen top right, inscribed "With un-grinching best wishes to Jed...." sold at $2600 (£1430).

Sold for $6500 (£3575) at the Rockefeller Plaza sale, but from an
entirely different source, was the undated watercolour drawing of the Cat in the Hat, below right, perhaps Dr Seuss' most famous creation.

Lacking the jacket and spine and generally soiled, torn and browned, but with the original watercolour drawing on the front pastedown - inscribed to the placard held aloft in the elephant's trunk, "For Charles Henderson Brough who is really too old to be reading books like this...", a 1940 first of Horton Hatches the Egg made $6000 (£3300) in a Bonhams & Butterfields (San Francisco) sale of June 28.
