A Sevres urn lamp

Celeste and aqua are my favorite colors. This urn was bought to Dorita several years ago a January. In fact Sergio saw it and as he knows that the color was my favorite took me there and we purchase it at once. It was very dirty and the shade was my invention, you can see it in the second picture the last object. The painting is wonderful and it is signed but I do not understand what it says (last picture). We have not separated the parts but there is no visible mark. The quality of the gilded cartouche (last picture) suggests it is French and perhaps Sevres; also the Celeste that is a sort of mixed points of different colors points to a Sevres manufacture, replicas have a plain background colour. The lady in a garden with a simple gown, and simple hair arrangement, stick and dog reminds the portraits of Marie Antoinette in the Trianon http://www.galleryhistoricalfigures.com/figuredetail.php?abvrname=MarieAnt_Trianon . It is in excellent condition, thus I think it is no so old perhaps end of 1800 beginning of 1900. Happy Christmas for every one tha see my posts, they gave me a great pleasure.
