Quality vintage French linen torchons or tea towels with a jaunty red, blue and green stripe at each long side. 
Unused, they still have the stiffening, but will soften when washed. They have slight storage marks from years in a trousseau, these will come out with laundering and perhaps a soak with some bicarbonate of soda. 
The torchons are hemmed at each end with a hanging tag and unfinished at the sides in the traditional manner.  They measure  50x63cm, 20x25"
