Sir Leslie Matthew Ward was a British portrait artist and caricaturist who over four decades painted 1,325 portraits which were regularly published by Vanity Fair, under the pseudonyms "Spy" and "Drawl". The portraits were produced as watercolours and turned into chromolithographs for publication in the magazine. These were then usually reproduced on better paper and sold as prints. Such was his influence in the genre that all Vanity Fair caricatures are sometimes referred to as "Spy cartoons" regardless of who the artist actually was.

Vanity Fair was a British weekly magazine that was published from 1868 to 1914. Founded by Thomas Gibson Bowles in London, the magazine included articles on fashion, theatre, current events as well as word games and serial fiction. The cream of the period's "society magazines", it is best known for its witty prose and caricatures of famous people of Victorian and Edwardian society, including artists, athletes, royalty, statesmen, scientists, authors, actors, business people and scholars.
