This is an art piece featuring knots displayed in a wooden frame. It was purchased in 1995 from a marine shop in Catharins Dock marina in London. (I believe it cost over 10,000 yen at the time, based on the exchange rate.) The frame is sturdy, with a wooden frame reinforced by metal edges, and the gold plates for each knot are beautiful. - Materials: Wood, rope, metal - Design: Knot display - Features: Nautical chart background - Size: Approximately 25cm x 33cm x 4.5cm Perfect for antique or marine sports enthusiasts, or as a collector's item. Thank you.
