French Oil Painting, Young Girl 18th Century Girl

A classical elegant jeune fille, or young girl  in Louis XV, 18th century attire with roses.  This magnificent and very large portrait is in the manner of Vigee LeBrun, just one of a magnificent pair of oils on canvas.  Her companion painting is a young boy in a green costume.  The paintings are on board and are housed in hand carved wooden frames with applied gilt, which were  created specifically  for the portraits.  I do not see a signature       which may be hidden under the  framing. 

Please view the companion painting, Young Boy.

I believe these paintings date to the early 1900's.
