This is a Pfaltzgraff, USA mug in the Cape May pattern with a lavender or mauve interior, foxgloves on one side and a cute birdhouse on the other side and a mauve blush interior.

The stineware mug measures 3.5 inches high by 3.25 inches in diameter and is in excellent used vintage condition. The pattern was made from 1998-2001, and this mug was made in the USA.  

What a pretty pattern!
