In the scene where Howard (Bernie Kopell) is showing Willy (Lee J. Cobb ) his new "wire recorder", you hear Howard's "son" reciting state capitals. The voice of Howard's "son" was June Foray, using the same voice she used for Rocket "Rocky" J. Squirrel in Rocky & Bullwinkle Show (1959).
In his autobiography "Timebends", Arthur Miller speculated that his unconscious mind picked the name "Loman" for Willy Loman, the protagonist of "Death of a Salesman", based on his conscious experience of being thrilled by Il testamento del dottor Mabuse (1933), which featured a character named "Inspector Lohmann".
The original Broadway production of "Death of a Salesman" by Arthur Miller opened at the Morosco Theater on 2/10/49, ran for 742 performances, and won the 1949 Tony Award (New York City) for the Best Play. Lee J. Cobb re-created his stage role in this television production.
"Death of a Salesman" won the Pulitzer Prize in Drama in 1949.
