I am brand new to the forum but I just aquired quite a few bottles and this one has me stumped. It is black glass I belive athough it is that dark olive color and it has a seal on the front which I am not familiar with. It appears to be blown glass as there are no seams and it has bubbkes in the glass. i could not really tell if ithas a pontil mark and the bollte doesnt sit level. Any help would be much appreciated! Thank you in advance.
