Hello, this item is a large Persian Ziegler Sultanabad carpet, woven in western Iran in the Sultanabad region, most likely dating to the late 19th to early 20th century, approximately circa 1890 to 1920 rather than strictly pre 1900. The rug features a classical all over scrolling vine and floral palmette design set on a light ivory ground, framed by a deep indigo blue border with repeating floral motifs, a layout characteristic of Ziegler workshop production intended for the European and American market. The drawing is balanced and open, with softened forms and a restrained palette of blues, madder reds, soft greens, and pale gold tones, all consistent with Sultanabad carpets produced under the Ziegler export model. The wool appears hand spun with a moderately coarse but durable handle, and the scale at approximately 15 by 18 feet places this firmly within the category of oversized room size carpets made for grand interiors.

The condition shows clear signs of age and use, including visible old suture repairs, areas of reduced pile density in high traffic zones, and general wear consistent with prolonged floor use. The structure remains intact, and the colors retain good saturation, particularly in the blues, which supports authenticity rather than later reproduction. Large Ziegler Sultanabad carpets of this size and decorative quality are valued primarily for decorative and interior use rather than rarity, especially when repairs and wear are present. Based on current market comparables for oversized Sultanabad carpets with condition issues, a realistic current market value for this example is approximately USD 3,000 to USD 5,000.
