This card is the stop, or halt, part of Stoptober.
Now this is a very curious card, which was also issued by the Imperial Tobacco Company of Canada.
The Ogdens version only has one printing, this one. However the Imperial Tobacco Company of Canada issued several variants - and the fascinating thing about that is that some versions show the soldier with no shoulder straps. Burdick`s catalogue, from where we get the C.18 code, adds that in some versions the soldier has a sleeve marking. This would be very interesting to find out more about, as may be possible to identify the regiment. So does anyone have any of these cards ?
I did have a quick look and the cap badge seems to be The King's Own Royal Regiment (Lancaster) - it certainly has the raised tail and outstretched front arm, but I will keep checking in case it is a Canadian badge.
The King`s Own Royal Regiment has had several similar titles, but a very long career as it was first raised in 1680. It spent the entire First World War on the Western Front, in France, as part of the British Expeditionary Force. The Lancaster part seems to come from the fact that it had been HQed there since the 1850s, at Bowerham Barracks.
