I know from the seller I purchased it from that this beautiful solid brass comb came from Pennsylvania, where it was used in the making of loomed coverlets of the sort I've included an image of in photos. One can tell from the gorgeous patina that it was indeed much used; it is in very good condition, the brass smooth with no pitting, but some oxidation to the surface, resulting in deepening of color and some reddening on the reverse side, which I love. Really a special feeling object, elegant and modern looking (it's got a sort of a Carl Aubock-ness about it for sure), heavy and satisfying to hold, and to me with a sort of iconic-ness, like the perfect articulation of "comb."
7 1/2" x 2 3/4" x 1/2 and in very good antique condition, much more beautiful in person. Weighs just over a pound.
