Volume 30 of Radio Archives Treasure! This 20-hour collection includes shows from the classic days of Radio. You'll find rare and obscure as well as mainstream radio shows from the 1930s, 1940s, and 1950s in the Radio Archives Treasures sets. These shows have all been restored with state-of-the-art CEDAR technology - the audio processing system used by major recording companies to restore older recordings. We expect the shows to be the best sounding copies available anywhere.
