Chinese armchair 19th

Chinese armchair from an auction in london (bought by my parents) and appraised by an expert at the british museum, confirming that it is a 19th century chinese armchair. As you will see, it has an exceptional ivory detail; I have not yet seen any on other chairs of the time. This kind of armchair was produced at the time for export to the west, or the oriental decor was fashionable. In beautiful condition, it was used only as a decoration at my parents' home for 40 years.
