Medium includes graphite. This relates to the official visit of Crown Prince Hirohito to Britain in May 1921 in the Japanese battleships 'Katori' and 'Kashima', an event of which Wyllie did two oil paintings originally commissioned by Kojiro Matsukata, President of Kawasaki Shipbuilding, Kobe, but now in the Museum of the Imperial Collections (Imperial Household Agency), Tokyo. The hoist of flags appears to be the one shown flying on the battleship 'Queen Elizabeth' (as flagship of Admiral Sir Charles Madden) in Spithead, in the background the painting of the two Japanese ships' arrival at Portsmouth under British destroyer escort. It distinctively includes a green flag, as top one of the hoist, annotated 'The only green flag in the book. (Submarine in sight / Starb[oar]d side)' and that if any of the evenly spaced flags needed to be removed it begins from topmast down. The sketch is apparently not by Wyllie, since lacking his fluency and the accompanying notes are not in his writing. It was presumably done carefully for him by someone else - probably naval - with specialist knowledge of the rules for dressing ships overall. PAE3354 is by the same hand. PAE3353 is by the same hand. [PvdM 6/18]
