As the above back cover says, "Even the machine protests..."
The front cover, by they way, reflects how I've been taking advantage of The Metropolitan Museum of Art's boost of public domain images from its collection. So on the front is a leaf from a Beatus Manuscript: “at the Clarion of the Fifth Angel's Trumpet, a Star Falls from the Sky; the Bottomless Pit is Opened with a Key; Emerging from the Smoke, Locusts Come Upon the Earth and Torment the Deathless”. Ca 1180. Spanish. Tempera, gold, and ink on parchment. The Metropolitan Museum of Art: The Cloisters Collection, Rogers and Harris Brisbane Dick Funds and Joseph Pulitzer Bequest, 1991. Thank you, Met!
For the same reason--thank you, Met!-- inside the chap is “Angel Applicant” by Paul Klee. Gouache, ink, and graphite on paper mounted on cardboard. The Metropolitan Museum of Art: The Berggruen Klee Collection, 1984.
