Thus, cards are usually decorated in five colors, but at three operations. The Aerograph Co., Holborn Viaduct, E.C., is prepared to quote for printing and coloring or for coloring only.

It is hardly worth while to consider the application of oil paints, as the result on such a small picture will always look heavy and crude. We may therefore confine our attention solely to water colors and the various commercial preparations which can be obtained for this purpose. Some of the most effective-results are obtained by using either the special transparent water colors or the so-called aniline dyes, but in the case of the latter, it must not be supposed that the coloring will be permanent, as there are but few of them which are really stable to light without some mordant, which cannot in this case be applied for fear of affecting the image. As the drawing is, of course, given by the photographic image, but little skill is required to obtain very pleasing results, and an even wash of color, say green, for instance, over a mass of trees or expanse of grass, will give...
