Torpedo Factory Artist Eric Margry is one of the few remaining hand engravers in the DC region. The images show him at work while creating a silver ring that features the number π (3.1415...). On its top plate, the ring displays the Leibniz series to compute π, at the sides you see the decimal representation of π to the first 25 digits.
The Picture Panel shows the whole story in one hangable piece. It is 24" x 20" in size.
