Vintage A&W Root Beer Mini Mug Red Logo "Ice Cold"

This is a vintage (pre 1960s) A&W Root Beer Mini Mug, with the words "Ice Cold" in the center. Some of the original wording has worn away. Otherwise it is in great condition! No cracks, chips, bubbles or clouding. Measures 3-1/4" x 2-1/2". A rare find and a great vintage piece of Americana!
