This rare find goes back multiple decades. It was a Japanese promotional Kentucky Fried Chicken (KFC) ceramic mug from 1986. The graphics are still very colorful and vibrant since it was not stored in direct sunlight. We don't believe it has been used since the inside is pristine. You may find the tiniest smudge marks at one part of the rim that likely were caused by stacking on another cup. All in all this mug is in excellent condition for its age.
This mug cup has graphics on two sides. It measures 9 cm tall (about 3.75") and 8 cm tall (about 3.25") so it would hold a standard sized coffee.
Quite a nice rare collectible from the early Japanese fast food industry!
