Clothilde

This 102 piece plywood puzzle has been imaginatively cut and was very challenging to assemble with its irregular outline and colour line-cutting throughout. The beautiful painting is unsigned and I have not been able to make an identification of the subject herself.
Please advise if you are able to supply any further information. Thank you.
