Canford was the subject of a documentary, THE HIGHEST BIDDER (which appears to be missing from the BFI database).
In 1992, a section of the tuck-shop wall was discovered to be an Assyrian sculpture assumed to be lost in the river Tigris 3,000 years ago, but brought to England by Sir Austen Henry Layard who rediscovered Nineveh.
It was previously dismissed as a plaster-cast.
The sculpture was sold at Christie's, in 1994, for £7.7m ($11.9m).
To celebrate the occasion, the headmaster gave all 500 pupils a Mars bar each.
The history of the Assyrian sculpture is detailed in a fascinating book by John Malcolm Russell:
From Nineveh to New York:
The Strange Story of the Assyrian Reliefs in the Metropolitan Museum and the Hidden Masterpiece at Canford School (Yale University, 1997)
