Royal Flying Corps
Recruiting Poster

According to a narrative from The War Museum Canada, "Lieutenant-Colonel (later Brigadier) C.G. Hoare, the RFC officer who headed the new training organization in Canada, moved quickly when he arrived from Britain in January 1917. He ordered that flying instruction commence at Long Branch on 28 February 1917, although buildings were still under construction and the first JN-4s had been completed and approved for service only days before. The largest school, Camp Borden, began flying training on 30 March 1917." This would date this recruiting poster to 1917.
