see below if I've put it in the right spot??
Arthur Lismer sent images of the damage from the December 6th, 1917 Explosion of the munitions vessel Mont-Blanc to the Sheffield Independent which published them. I would estimate that they appeared in the last week of 1917 or in the month of January 1918. Have these issues been digitized or are 35 mm microfilm copies available for interlibrary loan? These images og pen & ink sh=ketches should be quite easy to spot sine I expect that there were three or four used in the Sheffield Independent??
This newspaper (Sheffield Independent) is now available online up to 1938

I forgotb to add that this 2,9 kiloton explosion occurred in Halifax Harbour in Nova Scotia Canada and killed almost 2000 persons.
