A rather rare find for us, this attractive Chinese export porcelain reticulated undertray with blue diapered border, centered with a sunburst roundel, bears the family crest of JOHN ROSS of  Philadelphia. Ross was a very wealthy and prominent merchant and played an important role in the Revolution being by the Continental Congress to resource crucial war supplies and materiel for the Continental Army. To our knowledge most of the pieces from this service are in museum collections and seldom comes on the market.   $1900.
