Sally enjoys reading bloody thrillers written by Mickey Mallet - a spoof on Mickey Spillane, whose novels featuring Mike Hammer are just as gruesome as those Sally describes.
While the record album of the "Tristan and Isolde" music is never shown close enough to the camera for the movie audience to see it, it either is, or has been created to resemble, a typical 78-RPM album set of the 1940's of an RCA Victor recording featuring Arturo Toscanini conducting the NBC Symphony Orchestra. The cover art greatly resembles that of a 78-RPM album pressing featuring Toscanini conducting that orchestra. Toscanini was considered the greatest conductor of that era.
