BP Oil

This mug comes from BP Oil.  The mug is standard in shape, with the BP Oil Logo in yellow on a field of green (which are their trademark colors).  

On the other side is a rectangle of dark brown.  

When hot liquid is added, the dark brown rectangle clears to show the phase "Change Today To Be Better Than Yesterday."  It is unclear as to whether this mug was a corporate freebie (either to investors, employees or vendors) or whether it was sold in their retail stores.  The change is moderate, but complete and the mug is in good condition.
