This is a late 19th century to early 20th century leaded glass decorative window with textured slag glass pieces as well as cabochon jewel form glass pieces that form a medallion surrounded by bell flowers. The provenance, or history of prior ownership, also includes the original location, being a 20" x 22" piece from the front door of a home on Frawley Street in Boston, Massachusetts. The estimate is based on actual recent past recorded auction sales of comparables. Retail 'asking prices' can be higher and vary.
