This is the original art produced for the endpapers of the novel by Dean Ing, published in the hardcover 1st edition of the book, by Tom Doherty, 1990 (I show the published cover as well as endpapers for reference only) Done in pen-and-ink on paper mounted to light board, 15" x 20" with tracing paper overlay carrying printer's instructions this is fitting illustration for a novel about a breakthrough in stealth technology—an ultralight, ultrasleek plane that is  invisible to radar.
