The Locomotive Magazine Souvenir, edition no. 18 from 1912, published by The Locomotive Publishing Co. Ltd. is among the first railway magazines of its kind.
According to the British National Archives: "The Locomotive Publishing Company was established in 1900, and was probably the first organisation to make railway photographs commercially available. The LPC had sprung from the 'F Moore' trading company founded by two railway enthusiasts apprenticed to the Great Eastern Railway, A and A R Morton Bell. In 1896, joined by a third brother, W J Bell, they had commenced publication of the first popular railway periodical, Moore's Monthly Magazine, which soon changed its name to the 'Locomotive'. It drew on an archive of railway images the brothers had acquired from the steadily growing band of railway photographers, and the LPC successfully marketed these 'F Moore' photographs to a new phenomenon, groups of railway collectors and enthusiasts."
