Poster advertising Tropon, Henri Van de Velde, 1898, Belgium. Museum no. CIRC.992-1967. © Victoria and Albert Museum, London

This features a packaging by Van de Velde for the German food manufacturer Tropon and to create publicity. Amongst all the art pieces, this is my favourite one as I greatly appreciate the Art Nouveau style. This advertisement for egg whites adopts an abstract form rather than a realistic one. It illustrates the graceful yet structural elements of Art Nouveau; organic shapes, sweeping curves and decorative features. His design also evokes the shapes and colours of the egg. Even though it is highly stylized and abstract, main elements such as the colour of the egg, the roundness of the egg, is still incorporated subtly.
