This vintage Pyrex mixing bowl, model number 401, is a beautiful addition to any kitchen. With a white flower and butterfly gold theme, this mid-century modern bowl is made of milk glass, standing 3.5 inches tall and holding 1 1/2 pints.  The brand is PYREX and the product line is Butterfly Gold. This bowl is in great shape and is a vintage original, featuring vivid color, with no chips or cracks.  It does have a faint black mark that looks like it's under the glazing, and a few tiny scratches given it's age.  See pictures.
