Ace is that black residue on the stopper and "ink" stain on the inside of the bottle? What does the base look like? That one looks like it should have a ground pontil.....
This bottle seems more recent the seam goes through the lip. Taz yes there is a stain and residue on the on the stopper and bottle, It was full of liquid when I found it, I almost passed out when I opened it, I dumped it right away, it was dark brown liquid.
There are no markings on the base. You can see some tiny air bubbles in the glass.
