Mr Hall said he and Dylan had worked on the piece for two weeks, including weekends. Two were made to ensure at least one would reach its intended destination.
It was the first piece Dylan had worked on, "So he's pretty up there already," he said, although he had no plans to step aside in deference to the next generation for at least another decade.
Mr Hall's work, typically inlaid with fish, birds, seascapes, land images and sun rays as an expression of his concern regarding the damage man is doing to the planet, has earned him an international reputation.
His work is represented in the prestigious Bohlen Collection, in the US, which has been hand-picked from throughout the world.
