Michael: thanks for your help! Something tells me that the cork I found with the bottle was a replacement...it's not cut symmetrically and just doesn't seem to match the quality of the bottle.
Silverfish: It looks like the etched label is a thin glass film that is overlaid on the bottle. It would explain the imperfections and bubbles in the glass.
