Gossamer Steel by RJF International Corporation

 

This week's mug is a beauty from the RJF International Corporation. Originally sellers of industrial metals and materials, most of the company is now owned by other corporations.  This mug, however, is owned by me.  On the right side of the mug, it advertises the "Gossamer Steel Collection" and has the advert line "Changing the Face of Walls" above the company name at the bottom.  

On the left side of the mug is a beautiful garden scene with a large caterpillar on a branch above a bunch of leaves covered with darker leaves (highlighted in spots with red.)

When hot liquid is added, the caterpillar disappears from the branch, and the dark area below clears to reveal a beautiful butterfly.

The color change is almost perfect and the design is quite beautiful.
