A hard to find A & W Root Beer Coffee Mug. This A & W Coffee mug is shaped like an Irish Coffee Mug and is made of plastic. The Mug features the A & W Logo and I have never seen another like it. The A & W Mug measures 5 1/2 inches tall and has a diameter of 2 3/4 inches. This mug is in excellent condition and would make a great addition to an A & W collection.
