Vintage Germaine Monteil Royal Secret Bath Powder

Germaine Monteil Royal Secret Bath Powder 9 ounces I was gifted this secondhand. The poof is still in there, and there is powder in there, but I do not know its history. All I know is when I opened it (to check if it was empty....it was not), I was instantly transported back to my grandmother's bathroom circa 1982. I haven't smelled that smell since the 20th century.
