Underwood was commissioned to paint a camouflage subject (IWM:ART 2283). The file includes a pen and ink sketch proposal for the work (18), entitled 'Arabesque of First Sketch'(?), with a description. The size was agreed at five by three-and-a-half feet. Muirhead Bone saw the sketch and made some suggestions. There is a detailed explanation of the subject matter of IWM:ART 2283 at (57-61).
The file also includes correspondence regarding the French camoufleur, Andre Mare, whose work Underwood attempted to promote in England and with the Committee.
Further correspondence relates to IWM:ART1924, Underwood's portrait of McKean, VC, including details of his service (41). A work entitled 'French Girls Making Camouflage' was submitted to the Committee but declined. This work was included in the Royal Academy exhibition 'Camouflage', of which there is a press review at (68).
There is a leaflet regarding the Seven and Five Society, of which Underwood was a member, and a prospectus for Underwood's Brook Green School of Art.
