Here's a set of five Pyrex coffee mugs made to coordinate with the Corelle by Corning pattern called Crazy Daisy or Spring Blossom. The pattern was produced in the 1970's and was very popular. The mugs are all in excellent condition and appear to have been used little if at all. They are embossed on the bottom with the Pyrex logo. They can be used in the oven and microwave but not under a broiler or on the stovetop. The mugs stand 3.5" tall and hold 8 ounces of liquid comfortably.
