The last theatrical release of the film that featured RKO title cards was in 1949. When it was re-released in 1959, it was replaced by Buena Vista title cards and was the same way until 2001, when the film was released on DVD for the first time for its 60th anniversary and all references to RKO were restored. (The 1995 laserdisc release actually did retain the RKO titles before then.)
