The drawing is undated as are the others in this set. These are a set of drawings of display areas and captions for the Chatsworth Collection in 1957 - 8 (MP/CHI0215-6 and MP/CHI0238-9). Thus a date in the late 1950s is possible. These plans could equally relate to a later display arrangement in which case the plans could theoretically date to any time from guardianship starting in 1956. The creator of the drawings is not given.
