 Included in this "Collector Series" were Laurel and Hardy silents from Hal Roach Studios, authorized editions of Keystone comedies licensed by Sennett’s original backer, Roy Aitken, and a group of railroad films (Eastin was a lifelong rail fan).Consumer interest grew, and soon Blackhawk was offering a wide variety of vintage comedies, dramas, westerns, musicals, documentaries, serials, and cartoons.Unlike the home-movie dealers Castle Films and Official Films, which offered brief excerpts from longer films, Blackhawk released complete subjects as they were shown in theaters.
