What's My Line? Season 4 Episode 29

(1) This March 22, 1953 episode is the first episode which is lost to history in the time period after Gil Fates and Goodson-Todman ordered the cessation of the systematic destruction of kinescopes of "WML?" episodes in mid-1952. Fifteen more shows will suffer such a fate from here until a few months before the end of "WML?'s" CBS run in 1967. A full list of lost post-1952 episodes can be found in the notes to EPISODE #112 of July 20, 1952.
(2) MYSTERY GUEST: This long-lost episode marked the first of two appearances by veteran actor Pat O'Brien. His second mystery guest shot, on EPISODE #384 of October 13, 1957, was far more fortunate in that the kinescope of this later show still exists. One week prior to tonight's show, on March 15, 1953, Mr. O'Brien appeared in an episode of "General Electric Theatre" entitled "Winners Never Lose," in which he co-starred with Ward Bond and Ruth Hussey. - W-B (2008)
