Houston, TX: American Window Co., [ca. 1925]. 4to. 44 pp. Illust. title, photo illustrations, blueprints in black & tan (several large double-page folding). Printed illustrated green-gray softcovers, w/ raised embossed window logo for AWCO on front cover, lettering in black & orange, yapp fore-edges (minor dustsoiling, edgewear), still VG copy, retaining original printed thumb tab for A.I.A. First edition of this very scarce, and well-illustrated work on the newly invented windows produced by AWCO in Houston, TX which allowed for both upper and lower sections of double-hung window sashes to be pivoted in and cleaned. In the years before air conditioning became standard equipment for commercial buildings, and residences, the AWCO windows were installed in the Loew Theatre in Houston, Memorial Hospital in Louisiana, MO, the La Salle Hotel in Beaumont, TX, and Doctors and Hospital Building in New York. Lewis (1889-1944) was an oil engineer for the Texas Oil Company who when frustrated with being unable to just open windows a crack in order to work in the Texas summer heat, invented a double-hung window which could pivot open, and contracted with the short-lived American Window Co. to produce the window commercially.
