Square canvas swatch, approximately 1" x .75," from a heavily used Jeet Kune Do training bag personally owned by Bruce Lee. The fabric shows expected soiling from use and is encapsulated by CAG to a size of 2.375" x 3.375". Originally from the collection of Lee’s protege Herb Jackson, the piece is accompanied by a copy of a certificate of authenticity signed by Jackson’s son and an additional packet of provenance. A rare relic tied directly to the martial arts legend's training.
