Flanders was recommended to the WAAC by A E Richardson in January 1941. The artist also submitted some cuttings from the times of reproductions of his drawings of the interiors of key government offices and the Houses of Parliament. Flanders was not commissioned, but submitted work to the Committee, of which the following were purchased:
LD 1232, IWM:ART LD 1233 and LD 1234 purchased for 30 guineas in July 1941 [LD 1232 was lost with an exhibition en route to South America in 1942]
LD 1381 purchased for 10 guineas in September 1943
LD 2212-2213, IWM:ART LD 2214 purchased in July 1942 for 30 guineas
A further drawing, of St Andrew's Church, Holborn Viaduct, was purchased by the Ministry of Information and presented to the Colombian Minister by the Foreign Office. Other correspondence concerns Flanders's request for photographic reproductions for an exhibition being organised by the Society for the Protection of Ancient Buildings, the Ecclesialogical Society and the London Society, entitled 'Historic London Under Fire'; letters of recommendation of Flanders sent elsewhere in the Ministry; and Flanders's military service (he was called up in August 1942).
