Superman Heat activated Mug

It's a bird, it's a plane, it's superman!

Add a hot beverage and watch as mild mannered Clark Kent transforms into Superman!

Heat activates the mug and transforms the picture.  Clark Kent disappears and Superman appears.  When the mug cools off, it transforms back to it's original image.

Holds 16 ounces.  Do not put this item in the dishwasher.
