A beautiful Paris porcelain plate. Maison Jacquel,  Rue de la Paix, Paris.
 
  With Sevres type blue Celeste ground. Armorial for BOWES.
Gilded monogram, probably representing 'JJ' and 'B' for John and Josephine Bowes of Chateau du Barry, France and Streatlam Castle, County Durham, England.
 
  John Bowes, art collector, racehorse owner and philanthropist, purchased Chateau du Barry as a romantic wedding gift for his wife, Josephine Benoite Coffin-Chevalie in 1852. They later went on to build the Bowes Museum. 
 
  Josephine Bowes, actress, was central to John's later conversion to philanthropy. 
She purchased gowns from English Couturier Charles Frederick Worth of 7, Rue de la Paix, Paris during her visits at least yearly in 1858-65. One one later occasion, spending the equivalent of £114,000. It may have been during one of these trips, to this most prestigious street, they ordered a porcelain service from Maison Jacquel, successors to Feuillet, 3, Rue de la Paix, who had opened a store there in about 1856.  Chateau du Barry, originally a gift from King Louis XVI to his mistress, Mdme du Barry, was sold in 1862 to fund the public museum. 
 
The painting of Josephine Bowes by Antoine Drury circa 1850,  has a similar armorial in the top left.
 
Other royal commissions from Jacquel, include a service for Prince August of Saxe Coburg-Gotha and Princess Clementine D'Orleans.
