Source images from New York Hudson River Valley area newspapers and photographic equipment catalogs of the 1920’s and 1930’s used by Dennis Ashbaugh as the basis for “overprints” in Agrippa. The original plan was to print these images in “disappearing” or “fading” ink over the copperplate aquatint etchings in the book featuring Ashbaugh’s distinctive DNA-gels motifs. Opening the book and exposing the etchings to light or air would make the images gradually vanish, leaving behind only the DNA look. However, technical problems prevented the implementation of the fading ink, though an attempt was made to realize the concept in uncured photocopy toner. (See digital simulation of a fading overprint.)
