I'm a sucker for a barrel shaped box, and this is a sweet little one from early 1900's made for Atlas Tack Company, Boston, MA to hold steel carpet tacks. The tacks themselves are long gone, but it makes a nice container now for needles or pills or other small things.
Good antique condition with some dryness and light cracking to the unfinished wood. 2" tall x 1 7/8" wide.
