These are the only marks I saw. Andre Alice Norton (1912 - 2005) was an American writer of science fiction and fantasy, who also wrote works of historical fiction and contemporary fiction. She wrote primarily under the pen name Andre Norton, but also under Andrew North and Allen Weston. She was the first woman to be Gandalf Grand Master of Fantasy, to be SFWA Grand Master, and to be inducted by the Science Fiction and Fantasy Hall of Fame.
