An unusual relic of the space age. Dupont Magazine published an article on what Weigert called their fossil "embossments," and explained, "Franz Weigert, Bavarian engraver, creates precision replicas of fossils as prints. A silicon rubber cast is taken from the original. Embossing dies are prepared from the resulting replicas. Color-separation sets are made from photographs of the original" (Kappler, abstract).
