Possibly Unique and Historically Important WWI Photographic Archive of Jack Turner, Royal Canadian Artillery, consisting of approximately 510 original photographs taken illicitly by Corporal B H (Jack) Turner, 2nd Canadian Siege Battery, Royal Canadian Artillery. The photographs portray the unit’s service at the Somme, Vimy, Hill 70, Passchendaele, Lens, Arras, Canal du Nord, Cambrai, Valenciennes, Mons, Cologne and England. The images cover daily routines, comrades, trenches, guns in action, graves, carnage in the mud, German prisoners and much more. Most of the high quality contact prints (approximately 5.7 cm. square) were processed and printed by candlelight at the Front, and his German camera and equipment were hidden in the gun limbers, he wrote home in code for more film according to his daughter. Four hundred and thirty-three prints are contained in five albums and 73 prints are loose, most have his hand-written descriptions on the reverse. Accompanying the albums are also six large format (c.25 x 27cm.) photographs processed and mounted by him post-War and a large hand-coloured (40 x 47 cm.) photograpgh of four of his comrades; His annotated copy of ‘A History of the Second Canadian Siege Battery, June 1915-May 1919’ by Harold H Simpson with several of his own and official photos added. Jack and his unit were from Prince Edward Island, Canada and after the War, Jack became a farmer returning to photography only in the 1960s when he used a shed as a darkroom for his larger prints. This grouping is probably the best photographic archive we have ever had the pleasure to bring to market, the images capture all the horrors of WW1. Front line photography is extremely rare to find as cameras were restricted in the front lines due to the fear of the horrors of trench warfare getting back home and harming the war effort. This archive is a must for any serious collector, historian or institution
