Art Nouveau Aesthetic Movement Wood and Gesso Frame Very Old European

Art Nouveau-era (1890-1920) wood and stucco frame with floral, rope and bead motifs in relief. Origin: Likely France or Italy. Measurements 16 x 19 inches Good condition with some losses of the gesso commensurate with age. Please see the photos which will give a more detailed discription of the chips that exist. I could not find an exact twin of this frame so If you can tell me more about it I would appreciate it. I am pricing it on the high side until I can learn more about it.
