The memorial is regularly the subject or inspiration of other artistic projects. In 1931, Will Longstaff painted "Ghosts of Vimy Ridge", depicting ghosts of men from the Canadian Corps on Vimy Ridge surrounding the memorial, though the memorial was still several years away from completion. The memorial has been the subject of stamps in both France and Canada, including a French series in 1936 and a Canadian series on the 50th anniversary of the Armistice of 11 November 1918. The Canadian "Unknown Soldier" was selected from a cemetery in the vicinity of the Canadian National Vimy Memorial, and the design of the Canadian Tomb of the Unknown Soldier is based upon the stone sarcophagus at the base of the Vimy memorial. The Never Forgotten National Memorial was intended to be a statue inspired by the "Canada Bereft" statue on the memorial, before the project was cancelled in February 2016. A 2001 Canadian historical novel "The Stone Carvers" by Jane Urquhart involves the characters in the design and creation of the memorial. In 2007, the memorial was a short-listed selection for the Seven Wonders of Canada. The Royal Canadian Mint released commemorative coins featuring the memorial on several occasions, including a 5 cent sterling silver coin in 2002 and a 30 dollar sterling silver coin in 2007. The Sacrifice Medal, a Canadian military decoration created in 2008, features the image of "Mother Canada" on the reverse side of the medal. A permanent bas relief sculpted image of the memorial is presented in the gallery of the grand hall of the Embassy of France in Canada to symbolize the close relations between the two countries. The memorial is featured on the reverse of the Frontier Series Canadian polymer $20 banknote, which was released by the Bank of Canada on 7 November 2012.
