This has to be a rare little survival. And by little, in this case, I mean 12cm x 7.5cm and just 8 printed pages, sewn into fragile pink paper covers. My French is not perfect but it appears to be a 'tract' from the Societe de le Paix, part of the early and international peace movement. It claims to be a true story from London and would seem to me to be a moral story about a group of children who decide to play 'soldiers' and the way in which they come to decide that peace is the best option. Dated 1871 I think it's a wonder it has survived this long and I can't imagine where you might find another copy.
