New York City: The Psychological Corporation, circa 1950s. Two-dimensional wooden puzzle. Housed in original green cardboard box measuring 4 x 6.5 inches, printed in silver with manufacturer’s information and a capital letter indicating the subject of the puzzle.
Early examples of the Wechsler Intelligence Scale for Children Object Assembly Test, devised by Bellevue psychologist David Wechsler in 1949 as part of a wide-ranging assessment to measure intelligence in children. There were four different WISC Object Assembly Tests, each identified by a capital letter on the box: A for automobile, F for face, H for horse, and M for mannequin. (Wechsler also designed a series of Object Assembly Tests for adults as part of the Wechsler-Bellevue Intelligence Test.) Modernized versions of the original WISC puzzles are still in diagnostic use today. Classic examples of midcentury modern design, at the intersection of science and art. Please specify horse or mannequin in your order.
