Bold coloring, excellent condition. Whatman watermark. These are sometimes termed the Audubon/Havell prints, Havell being the primary engraver. These prints were produced by using as a basis the watercolor compositions or studies that Audubon accomplished mainly in the open field. These were then taken to London, where Havell's shop was located. Havell, often under the direct supervision of Audubon himself, would then engrave with precision tools a reverse image of the watercolor study onto copper plates, some plates being as large as 27 1/2 x 39 1/2 inches, and others being smaller for the smaller images. When finished, the plates were inked, the paper dampened, and then both were run together through the rollers of a press. The paper was thereafter pulled, or peeled off the plate, resulting in properly oriented black and white image, and then hand colored.
