Denny's Christmas Duck

In the 1980's Denny's Restaurants created many magic mugs, including this one, which is from a set of 4.  The mug features a Duck wearing a jaunty Santa cap and floating on his way to the South Pole. Astride his back is a frog, also with a Santa cap and carrying a gift.  The water is a dark blue, and the entire thing is framed in alternating colorful DENNY'S.

 When hot liquid is added, the dark blue water clears to reveal that the Duck is standing on a turtle wearing a Santa cap and there are also a couple of fish, also wearing Santa caps!

This is a fun and beautiful mug!  Color change is very good, as the water  you see is a light blue behind the Thermochromatic ink.
