Fine Bone China.
The bottom of the cup reads: Avon Blossoms of the Month Series, May Lily of the Valley, Avon, 1991.
The cup and saucer have a fine gold trim.
Saucer is 5 1/2 across. Teacup is 2 1/4 tall.
It is in excellent condition, it has never been used.
It would be a nice addition to the china cabinet
