This is a gorgeous bone china blue and white floral chintz mug by Maxwell Williams in a pattern called Antique Blue with a pretty pedestal shape.

The bone china mug measures 4.25 inches by 3.85 inches in diameter.  The mug is in very good +++ used vintage condition with no chips or cracks.  Made in 2005 in China.

There is a bit of discoloring inside, as shown in the photo.

I just love chintz!
