This is a very interesting image, photo undated, taken by James Thorley Wrench, Saville studios, Hoghton street, southport (business stamp in reverse). Wrench and his parents emigrated to Canada in april 1911 and lived in torontoi. In 1917, James Thorley Wrench attested for the Canadian Expeditionary Force, no record as yet of if he ever went overseas.
The shop in Southport will have closed when they emigrated and so this image may well be pre-WW1.
Unless James had kept some of his old printing cards and used them later on when he was serving, anyway, I have looked at various possible locations in Lancashire but nothing matches, also looked at Salisbury Plain camps but many of those only popped up when War broke out and this photo may well pre-date 1914.
Any ideas please?
