 As a commercial artist he designed numerous posters and advertisements, especially in the 1910s and 1920s, for such brands as Rowntrees chocolates, Guinness and Bovril, and his series of advertisements for the Underground Electric Railways Company (the London Underground) were very well known; his work as a wartime propagandist includes the poster for which he is known above all, the Lord Kitchener poster design, which first appeared on the cover of the weekly magazine "London Opinion" on 5 September 1914.

 Massine created the world's first symphonic ballet, "Les Présages", and many others in the same vein.
 Besides his "symphonic ballets," Massine choreographed many other popular works during his long career, some of which were serious and dramatic, and others lighthearted and romantic.
 He created some of his most famous roles in his own comic works, among them the Can-Can Dancer in "La Boutique fantasque" (1919), the Hussar in "Le Beau Danube" (1924), and, perhaps best known of all, the Peruvian in "Gaîté Parisienne" (1938).
