A copy of "Modern French Painters" (1923) in my library, once in the possession of the artist Steven Spurrier (1873-1961), has the following dedication from Jan Gordon:

"To my old pal Spurrier

in memory of the purest art we ever touched. Dazzle.

Jan Gordon"

This is a wonderfully evocative connection with the story of the dazzle-painted ships of WW1, in which both Jan Gordon and Steven Spurrier were involved. In "The London Roundabout" (1933) Jan Gordon reminisces about those times: "I was in uniform, lieutenant in the R.N.V.R., although I had never been nearer to the quarter-deck than the Royal Academy Schools, which were the headquarters of the Naval Camouflage section, under the well-known marine painter Norman Wilkinson."
