In late 1926 American silk manufacturer H.R. Mallinson & Co. introduced a bold new line of printed silks, twelve landscape designs, each available in from eight to twelve colorways (color combinations) on three different ground fabrics. The designs celebrated America's national parks - then only a decade old. The designs represented all the usual styles necesssary for making clothing: allover prints, horizontal stripes, checks, a border design. This sheer plain weave fabric, Mallinson's Indestructible chiffon voile, is printed with the design depicting Mammoth Hot Springs, at Yellowstone National Park. Selvage width; selvage inscription. Judging from drawings by free-lance textile designer Walter Mitschke in the collection of the Museum of Fine Arts - Boston, Mitschke designed this print and a few others in the National Parks series.
