Guerlain Jicky Extrait No 453, which is the 80ml (2.7 fl.oz.) flacon carre.  These are actual pictures of the item for sale.  This is a sealed NOS item dating to the 1930s or 1940s. The last picture is of a different bottle to give you an idea of what's inside.  Before it was unwrapped, the example box weighed .3 OZ (10g) less than the one for sale in this listing, so the one in the listing should be more full than the example.
