This is an early 20th century, about 1900 to as late as the 1930's French Louis and Victorian style button tufted back, 8-leg sofa with damask upholstery. The materials and hardware used for the construction, which may be visible on the underside will also help determine age. Without maker marks, tags or labels where that was made or by whom cannot be definitively stated. The estimate is based on actual recent past recorded auction sales of comparables. Retail 'asking prices' can be higher and vary.
