Fire King 1950s pair of mugs ~Burnt red ~ Off white~"D" handled for larger hands

Fire King milk glass "D" handled~ coffee mugs.A pair of Vintage one is burnt red and the other is a off white. I have been told the "D" shape handle makes the mug easier for people with larger hands and fingers to hold the mug securely in their hand. One is Burnt Red Milk Glass and the other is off white. Both Vintage mugs are in excellent condition from the 1950s. No cracks, stains, chips or repairs. Both are marked Fire King on the bottom. Please see photos.
