The drawings fall into two main groups. The first group comprises drawings, executed in pen and ink, graphite pencil and watercolour gouache on paper, to provide illustrations for the academic publication of the excavation seasons 1920-1957. The first two files in this series comprise the majority of the art work that supported the thirteen-part definitive report of the 1920-1923 excavations in the Annual of the British School at Athens, volume XXIV (1920) and XXV (1921-1923), and Chamber Tombs at Mycenae (Society of Antiquaries: Archaeologia, 82), 1932, under the editorship of A. J. B. Wace. Notable archaeological draughtsmen who supplied illustrations include Piet de Jong (1887-1967) and Emile Gilliéron fils (1885-1939).
The second group comprises the pot drawings in ink and graphite pencil on paper, produced primarily during the excavation and study seasons 1959-1969. The majority provide scaled section drawings of pottery; additionally, some also provide details of decoration on the pot body.
