19th century large French portrait signed P. Le Chevalier ( 131 cm )

19th century large french portrait signed p. Le chevalier ( 131 cm ). This wonderful portrait has been professionally cleaned and has had some light restorations over time. It I signed p.le chevalier of which we have not found anymore info which was surprising to us as some details of this painting are done extremely well. It has a also bee suggested that p. Le chevalier might have been the sitter but again we could not tell for sure.
