Among the other vegetarian music artists besides McCartney depicted on the stamps are Bryan Adams, Joan Jett, and the Pretenders' Chrissie Hynde. Also featured are such wide-ranging luminaries as Leonardo da Vinci, Mohandas Gandhi, Leon Tolstoy, Pamela Anderson, Natalie Portman and Ellen DeGeneres.
