Six rosewood Italian chairs

What a stunning set of dining chairs! These six dining chairs are made in Italy but from an unkown manufacturer. They were probably made in the 1970's. They remind us of the Superleggera chair by Gio Ponti. They are not by his hand but certainly of the same quality! The seats are reupholstered and in amazing condition!
