This is an antique 19th century, Victorian era, about 1830 - 1840, secretary desk that is done in a transitional style combining Biedermeier and American Empire. The body is veneered and the graining is part of the aesthetic decoration as well the carved Dutch rippling elements around the borders. The estimate is based on actual recent past recorded auction sales of comparables. Retail 'asking prices' can be higher and vary.
