In 1988 a group of cartoonists, collectors and lovers of the art form came together as The Cartoon Art Trust with the aim of founding a museum dedicated to collecting, exhibiting, promoting and preserving the best of British cartoon art. After a decade of exhibiting in smaller venues, in February 2006 the Cartoon Museum opened to the public at its current home in central London, very near the British Museum.

The museum has three main galleries displaying original artwork from British cartoons and comics, past and present. Temporary exhibitions since 2006 have featured Private Eye, William Heath Robinson, Steve Bell, Giles, Pont, H.M. Bateman, Viz Comic, Ronald Searle, The Beano, Ralph Steadman and many other luminaries. At the heart of the museum lies its growing collection of cartoons, caricatures and pages of comic-strip art. The foundations of modern British political and social cartooning can be found in works by Hogarth - whose social satires are regarded by many as the foundation of the British cartoon tradition, James Gillray and Thomas Rowlandson. The permanent collection also includes works by a number of fine Victorian cartoonists including John Leech, George Cruikshank, George Du Maurier and John Tenniel. William Heath Robinson - whose name is synonymous with outlandish and hilarious contraptions - hangs with his contemporary, H.M. Bateman, two of the most successful cartoonists of the first half of the 20th century.
