A curious one, crafted of two different pieces of horn, one fit inside the other to create a tiered form, with a beautiful carved wooden bottom, threaded neck, and turned wooden stopper. Plus, a heart on its front, and which follows the curve of the flask so I have to think was forged just for it. I believe this was made to hold gun powder--like a powder horn, except pocket sized. I've found a few other examples of powder flasks of this scale out there, but this seems to be quite a singular one, 19th century, and I think really terrific, perhaps with the heart a good luck charm, keeping its owner safe and sound.
5" t x 2 1/16" w x 1 7/8" d and in excellent condition, and it could certainly be filled with something now.
