Insert shots show the three envelopes in which Eddie anonymously mailed money to his father, Uncle Norman and Tina. The addresses are simply, "Tomorrow Magazine, Los Angeles Cal." (typed on Eddie's toy typewriter, with random spaces in most of the words). The one addressed to his father is spelled, "MIST ER TOM CORBIT" (an unlikely misspelling of his own last name), and the one to Tom's secretary is (mis-)spelled "TIANA" (rather than Tina). The letters bear a "PB (Pitney Bowes) Meter" impression, with the date, JAN 6, '70 (the episode first aired in March, 1970) and the mailing location, CULVER CITY, CALIF., which is the location of MGM Studios, where the show was produced. While a "PB Meter" impression is valid postage in itself, there is an additional paper stamp stuck over the right portion of the metering, with its own cancellation.
