'Zeppelin' by Gamy-Montaut, Published by Mabileau & Co., Paris, 1915, Framed & glazed, overall 54 x 102 cm. The Gamy-Montaut prints were produced by the pochoir process in which the outlines for each image were drawn onto lithographic stones and printed. Using these uncoloured prints as a template, elaborate stencils were cut for each colour. Water-colour was then brushed onto the image through the stencil. The colouring process was quite complex, with each print taking several days to produce.
