I picked this one up last week at a flea market. I have been soaking it to remove gunk that had dried inside it. The bottle is amethyst, 9 1/2" tall and 2" diameter at base. It has one sunken label panel. What intrigued me was the bottom of the bottle, an embossed bird. I did a search on this site and could not find anything similar. My thought was the bottle might have originally contained dressing/olive oil...any thoughts to it's purpose and maker?
