You can tell the story of this kiss by putting the cards in what order you please, of course.  Someone with a lot to say in 1916 has covered the backs of these with small handwriting, in French: neither my French nor my eyesight is up to finding out what was so important in 1916.  There is no address or stamp: just this long barrage of text.  Lost erotic short story or an attempt to borrow money?  In any case, the kiss is still a kiss
