David T. Darling- ''Pine Tree''- water-graph in colors, ca. 1930, signed in pencil, pristine colors. Darling held a one man show at the Art Center in New York City of a new type of decorative water-color which he called 'Water-Graph' which he made by a secret stencil process of his own invention. He used seven, eight or more stencils to obtain the well-defined outlines and transparent watercolor applied with a drybrush to produce the subtle gradations of tone. The general effect is of a beautifully handled color woodblock print, but with richer tonal effects and more shading. The process gives the appearance of something which is between a transparent, brushed watercolor and a pastel.
