This amazing coffee mug is a dark color when cool, add a warm drink and watch
the dark coating fade away to reveal a vintage B25 Bomber and a P51 Mustang aircraft on it.
These 2 planes were built by North American during World War II.
When the cup cools down it returns to the dark color until refilled with another warm drink.
Mug size 11 oz, hand wash only, microwave safe.
