A detailed examination of anomalies in an article on Lee Harvey Oswald and an adjacent advertisement show Nat Sherman intentionally included the irregularities in his ad.

Robert E. Webster represented a plastics manufacturer at a trade show in Moscow during 1959. He met a woman named Vera and starting dating her. After the show ended, Mr. Webster defected to the Soviet Union.

The overturn of the convictions in the Prague trial of 1952 by the Czechoslovak Government sent a clear signal to the Kennedy administration that a relaxation of tensions in the cold war was possible.

The appearance of intrigue surrounding the reported defection of Lee Harvey Oswald suggests many possibilities.

Nat Sherman had a special interest in the Rosenberg case of 1950-1953 and the Prague trial of 1951-1952. We find many coincidences of erroneous Nat Sherman' advertisements with articles on these spy trials. More significantly, Nat Sherman published an encrypted message on the same day as the doomsday article on the Rosenbergs.

Aline Mosby interviewed Lee Oswald in Moscow probably on November 13, 1959. Oswald said: "I'm a Marxist, ... I became interested about the age of 15. From an ideological viewpoint. An old lady handed me a pamphlet about saving the Rosenbergs... I looked at that paper and I still remember it for some reason, I don't know why."
