This article addresses the techniques and materials used in the production of The Band Concert (1935), a seven-minute Technicolor Mickey Mouse cartoon. An investigation of the standardization of drawing and line in the context of the histories of technical drawing and the industrialization of animation is followed by a description of the use of colour, particularly of the relation between the inks used on the cels and the dyes used in film prints at the time. The author asks whether it is possible to articulate a materialist theory of the aesthetic, ethical and political meanings of technique and technology without losing sight of the techniques and technologies themselves.
