The House of Commons is the custodian of an important collection of art and artifacts reflecting Canada's social and political history. Many of these works are displayed throughout Parliament, including its committee rooms. This painting, Ghosts of Vimy Ridge, is currently on loan to the new Canadian War Museum, but its permanent home is the Centre Block's historic Railway Committee Room. Portraying the flickering spirits of departed Canadian soldiers making their way toward the summit of the ridge, it was painted in 1929 by Australian artist William Longstaff and purchased by Captain John Dewar, who donated it to Parliament in 1931.
