(CBS News) A Boston auction house is showing 290 artifacts connected to the assassination of President John F. Kennedy. The items include the wedding ring owned by Lee Harvey Oswald, Kennedy's assassin, which has never been seen by the public.
While Oswald's simple gold ring almost slipped through the cracks, it is now providing clues as to what the gunman may have been thinking the day he killed JFK.
In 1961, after Oswald defected to the Soviet Union, he bought the ring for his Russian bride Marina Prusakova. He and his wife later moved to Dallas and separated.
