Offered is a vintage new boxed splash bottle of eau de toilette (90%), likely dating to the early 1960s. Size is 3/4 of an ounce or 22.2mL, of which about 19mL is left. This bottle is about 95% full. I cannot say if it was opened or whether it has simply suffered a small amount of evaporation. The liquid is clear and without any increased viscosity. There is some shelf wear and a tear to the innner box (not visible from the outside).
