Very special antique salesman sample button cards dated before WWII from "Colt". They have charming handwritten part numbers and some with lovely hand written notes. A very few have them have a missing button, but that is because the particular color or size was discontinued.
These sample boards are 9 7/16" x 6 15/16" on thick white paper board. They do show their age somewhat but are mostly in really nice condition.
These would look nice framed, or not, hanging on a wall in a sewing room, or in an antique display.
