 For many years, only the first half of the kinescope of the live  1954 TV version of "12 Angry Men" (shown as an episode of this  series, and upon which the movie version  (_12 Angry Men (1957)_ (qv)) is based) was thought to survive, and  had been in the possession of the Museum of Television & Radio since  1976. In 2003 a complete 16mm kinescope was discovered in the  collection of Samuel Liebowitz (former defense attorney and judge)  and was also acquired by the museum.
