Pileated Woodpecker Plate CXI, 1829
Engraving with Aquatint
27 x 37 in
In the 1970s, fourty full-size images in an edition of one thousand were produced in Leipzig, Germany using somewhat antiquated techniques. The collotype process is known in the trade as Leipzig Edtion. This is a limited edition and is double elephant sized. Under magnification, these early Leipzig prints reveal no geometric pattern of dots. They are still being published generally with the name "Ariel Press" in the margin. These prints have no watermark and have false plate marks.
