Just came across this on the Tradition Facebook page a Swedish book published in 1914 (?) about playing with toy soldiers, sadly in Swedish (which I don't read or speak) but has overtones of H.G.Wells as it seems to use various methods of 'shooting' the toy soldiers with projectiles .
You can see the whole book here Hur man för krig med tennsoldater sida 1 faksimil | Litteraturbanken
and I can make out enough of the words to get the jist of it I think .
I've never heard of this book and don't think it was ever reprinted or translated .
It has photos of some of the figures used in the game , flats or semi-flats ?
This advertisement is in the back of the book . This is a fascinating book and seems very rare to buy and probably very expensive so we are lucky to be able to view it on the above link .
