On the cover

Twins Anna and Elena Balbusso pieced together traditional art media—acrylic, gouache, pen, and pencil—using digital techniques to create this issue's cover. The image, which accompanies "Learning From the Man Known Only as 'Him,'" on the use of cadavers in medical schools (p. 52), imagines a donor's body as an opening in the hedges of a memorial garden, representing the crossover from life to death. The award-winning illustrators' past clients include The New York Times, The New Yorker, and Reader's Digest.
