Vintage Fire King Yellow & Brown Stackable Coffee Mugs set of 4

This is a great looking set of 4 Fire King mugs made in the USA sometime in the 1960s-70s. Brighten your dining experience with this set of yellow and brown glass mugs. Perfect for enjoying your favorite beverages. Each one measures just over 3.5 inches tall. They are made to stack and look good doing it. My parents had received them as a wedding gift in the early 1970s. They have been in storage ever since. I believe they are unused. ( my mom doesn’t ever remember using them) Paint is crisp. A fun eclectic addition to your drink wear.
