“A box of Diamond Brand ‘double pointed-tapered-flat polished white birch’ toothpicks from abou the 1960s claimed to contain ‘the most perfect toothpick made.’ The toothpick’s quality . . . was touted on every panel, including the bottom, which bragged that the product was ‘made in U.S.A. by American workers of American materials.’ The bottom of the box said also of the Diamond trademark on the top that ‘its use on a package of wood products insures Diamond quality of both materials and workmanship—Every One Perfect.’”
