At first glance this appears to be a 'pen and ink'. But it's not. Look at the second image. This is an image printed from a hand engraved plate. Image was 'pulled' from a dry copy of an original. Plate is german silver (nickel silver) about 9"x6". Light cuts with an onglette and chasing hammer. Plate was polished then inked with fingerprint ink. Into a hydraulic press at about 20 tons. Result is as you see it.
