Today's mug is one of two I found very near identical. The mug is black and on the right is a slightly darker area with a drawing of the Golden Snitch from Harry Potter. On the left side of the mug is a Hogwarts banner above a heraldic shaped darker area with the H in the center and another banner at the bottom which says "Draco Dormiens Nunauam Titillandus" which is the Hogwarts Motto. (Never tickle a sleeping dragon.)
When hot liquid is added to the mug, the dark areas clear. On the right side of the mug it shows a patchwork design that says "I'm a Catch" and on left side the heraldic shape shows animals which represent the four houses of Hogwarts: A Lion (Griffindore), a Serpent (Slytherin), a Badger (Hufflepuff) and an Eagle (Ravenclaw.)
The mug is brand new, and still has it's original tags.
