Service SheetsPhiladelphia: Architectural Service Corporation, 1916-1922. Single sheets of paper, most printed two sides, one in color, one partially in color. 55x42cm. Housed in a portfolio with brown buckram back and corners, brown paper board covers, brown cloth sides and paper title label on the front cover. A complete set, lacking one sheet (2-2), and (42-1), which according to the index was "to be published," plus four additional sheets not found in the index (11-11,12-4/5, 102-AB, and 253-1), for a total of 105 sheets. Each sheet provides detailed drawings "showing the uses of up-to-date building materials and specialties. They are not only exceptionally well drawn, but also unusually accurate," according to American Builder in 1919. Topics include: design, structural, plumbing, heating and ventilation, hardware, equipment and electrical. Service sheets on roofing give details on tin, glass, asbestos shingle, slate, and wood shingle roofing and building. Service Sheet 43-2 shows the specifications for the copper roof on the Woolworth Building in New York. A mine of information for restorers, architects and builders. The sheets are printed on a very durable paper and show minor wear -- a few creases and short tears; the portfolio front cover is rippled at the bottom edge from a liquid spill, stain on the bottom cover, and over all soiling; the title label is bright. The sheets are very good to near fine, and the portfolio is in good condition.
