George V was on the throne and the Great War was still raging when this photograph was taken. Was the Commercial League a precursor of Londonderry's current amateur league? Perhaps so.
For most of the latter half of the nineteenth century and the first half of the twentieth century Londonderry's pork trade was the main provider of male jobs in the City, certainly on a consistent basis. The majority of the pork stores were concentrated along Foyle Street. At the tine this photograph was taken the largest of these were Buchanan Bros, Mark Roulston & McLaughlin and Biggers Ltd. The individual second from the left on the back row, (W Carruthers), hailed from Culmore and was an employee of Biggers Ltd.
