These are a set of 4 matching vintage mid to later 20th century upholstered chairs with tufted shell or channeled backs; two are side chairs and 2 are arm chairs. Technically, these are not Queen Anne form at all, which would have a different form shape and simplified legs. The feet on the arm chairs are stylized as Chippendale Revival, though a loose interpretation. There are no tags or labels on these to indicate maker. These were likely manufactured in America. The estimate is for all four chairs together and is based on actual recent past recorded auction sales of comparables. Retail 'asking prices' can be higher and vary.
