I look at old handmade tin cookie cutters all the time, but rarely feel compelled to buy one, but then this little bird, as tiny as they come, with kind of a funny shape to the head and very charming swallowtail sort of end. I'd be very tempted to use this to make many many dozens of little bird cookies, but maybe better just to perch it. Very sweet.
2 1/8” l x 1 1/2” x 3/8” and in good antique condition, with just a bit of separation between the cutter edges where they meet at the belly of the bird.
