 Whilst cracking open a safe in a Swiss lawyers office, Bond reads a  copy of "Playboy". This is a nod to the fact that "On Her Majestys  Secret Service" first appeared in "Playboy". "On Her Majestys  Secret Service" was the first Ian Fleming (I) (qv)s James Bond  novels to be serialized in the magazine, appearing in the May 1963  issue of "Playboy". It was followed by  _You Only Live Twice (1967)_ (qv) in the April 1964 issue.
