DescriptionU.S. Sketch Board, model 1913, made by Keuffel & Esser Co., New York. No date, circa 1890-1910. Pine wood, 12-1/2" wide 15" high x 5/8" thick; overall thickness with tacks and bottom knobs 1" thick.

Back has imprinted text in black with model name and number, directions for use, manufacturer's name. See notes for transcription. Reference materials related to this era are not readily available at time of cataloging. Date range represents a likely period of production; the item may be earlier than 1890. The board was apparently intended for field use in making sketches while doing survey work. The compass which uses only North marking was to orient the board before starting a drawing. Various scales in black appear at the top front. Ones at the right: inches; hundreds of yards 6" = 1 mile; hundreds of yards 3" = 1 mile. At the bottom is a scale in black for guiding perspective drawing. K&E main office and factories were in Hoboken during the period when this was manufactured.
