I am new to this forum, but I see there is much knowledge here. I am in the antique business and see quite a few bottles in my travels, but I have always ignored them due to my lack of knowledge. I have recently decided to start learning more about about bottles, since I see so many. I recently found this unopened poison bottle. This bottle is 3-1/4" tall, and has three sides, two of which are marked "POISON", and one side is blank. The bottle is full of triangular-shaped tablets with a wad of cotton between the cork and tablets. Any information about the tablets would be appreciated. Also, is an unopened bottle a rare find? What is the bottle worth? Thank you.
