This is an English bone china Roy Kirkham, England mug in a pattern of pink wild Roses with bronze foliage on white from the 1990s from a series called Cambridge Collection.

The pretty pink and bronze Roses mug measures 4 inches high by 2.85 inches in diameter and is now a discontinued pattern.

The mug is in excellent used vintage condition with no chips, cracks or wear and looks like it has never been used. So pretty!
