Francis Campbell Boileau Cadell (Scottish, 1883-1937) - Interior, 30 Regent Terrace with Easel (Oil on canvas) - Whilst the brushwork of Interior, 30 Regent Terrace with Easel is elegant in its impressionistic application of paint, Cadell’s quick-witted and playful personality has not escaped the painting. Through the central doorframe we can see a painting on an easel, identifiable as Cadell’s Interior, Regent Terrace of 1932-33.
