932. Poison bottle, this article states:
To distinguish them from non-lethal products, poison bottles were made unique and dramatic in color, texture and shape. Colors like cobalt blue, honey amber, black, and emerald and several other shades of green were used to ensure they stood out from the other bottles on the shelf.
Poison bottles were also designed with unique textures: latticework, raised ridges, dots, diamonds, horizontal or vertical ribbing, or hobnails. Also, embossed lettering warned, "DEATH," "POISON," "POISONOUS," or "NOT TO BE TAKEN INTERNALLY."
More photographs of them can be seen at the Antique Poison Bottle Hall of Fame.
