A poignant slice of social history, does it commemorate the end of The Great War perhaps? The building looks quite unique so should prove pivotal in locating the scene, if it is still standing of course.
Unposted with the, as usual standard template on the back and nothing else, no date or message or anything!! The numbers 1403 are enclosed within the space for the stamp
Lightened it up a bit. Don't think there is enough room for the word "Temperance" in the notice. I think it looks more like "Esperance" if there is such a word? A right scruffy looking bunch of service men though. So there's no Bootnecks there. My spellchecker never picked out the word "Esperance" so maybe there is such a word too. Out dictionary now to check up.
What about that lamp-post design? Looks unusual too. The weather looks a bit on the windy side as the flags seem to be flapping wildly. Maybe it's been raining. Perhaps that accounts for their general untidiness.
