SUMO is a book series by publishing house TASCHEN, so named due to their size.

Featured portraits include Catherine Deneuve, Nicolas Cage and Mickey Rourke.

In keeping with its title, the book weighed over 30 kilograms (66 lb) and measured 50 by 70 centimetres (20 in × 28 in).

Owing to the size and weight of the book, a bespoke stand was designed by Phillipe Starck to support it.

This was subsequently sold at auction in Berlin on 6 August 2000 for $430,000, becoming the biggest and most expensive book produced in the 20th century.
