Found this on the interweb , French WW1 era I would say, I think I've seen the child as a model in another similar card . Google translate gives me - "to give the artillery" ? and the blue stamp across the card seems to say - "56th Regiment Territorial"? , I wonder that is something to do who posted it ? . The figures are interesting large scale ones, I think I've seen something like them before , they could be Bon-Dufour composite about 5" tall (thanks Brad DeSantis for the info in a previous post) . I wonder if it was hand coloured ? and lke the use of real earth for the trenches - don't think the young chap is going to miss at that range!
