ERIC ED541428: Nursery-Kindergarten-Primary Education in 1924-1926. Bulletin, 1927, No. 28
This 1927 federal bulletin on nursery, kindergarten and primary education was issued by the United States Bureau of Education for school administrators and teachers. Its two pictures are plain floor plans drawn in ink, one of a kindergarten room with a coat room, sink, supply table and alcove, and one of a grades one to three classroom with cubicles, chalk rails and a reading table. A designer could take from them the clean architectural diagram style, with dimensioned labels, hatched walls and furniture drawn as small rectangles in rows.
