Triangle Amber Glass POISON Bottle [J.T.M. & Co.]

Vintage Poison Advertisements/Labels

I found this triangular amber POISON bottle a few days ago embedded in mud and sand next to the river.  Surprisingly, it was neither broken nor cracked in the slightest (until then, I had only ever found the sad broken remains of poisons), so I brought it back with me.  

Rudy Kuhn's Poison Bottle Classification by Shapes

Based on the classification/naming system for poison bottles that Rudy Kuhn coined, this poison bottle is a KT-5.[1][2][3]

The 'K' stands for 'Kuhn', the 'T' stands for the bottle's shape--Triangular, and the number '5' denotes the order in which it was originally entered in the books.[5]

This poison bottle stands 3" tall.  The word 'POISON' is embossed across the entirety of just one of the sides.  It has sawtooth ribbed edges.  

The base is embossed with 'J.T.M. & Co.', presumably the manufacturer of both the contents as well as the bottle.

These specific poison bottles were manufactured from 1890-1910.[6]  

It is mouth-blown and has an applied/tooled lip.[7]
