Johnson, Riddle and Company (fl. c. 1910 - 1974) was early to mid-20th century graphic artists and printers active in South London. They are best known for their exceptionally composed and highly graphic World War I (1914 -1918) propaganda and recruitment posters. Specifically, they received a lucrative contract from the Parliamentary Recruitment Committee to produce posters between 1914 and 1916. Later they issued many posters promoting the London Underground. Their most significant cartographic work is the serio-comic map Hark! Hark! The Dogs Do Bark!, a satirical look at World War I. They remained active until 1974.
