Lost in time and space... how can you enjoy these classics?
All seven episodes of this story, which sees the Doctor and his companions meet explorer Marco Polo in 13th-century China, are lost. However, DVD box set The Beginning, which includes the first three Doctor Who stories, also features a condensed 30-minute form of 'Marco Polo' as an extra.
This version of the story consists of 'telesnaps' (photographs taken off-screen on original transmission) set to an edited audio track. The entire story exists as an audio recording, which has also been released in full on CD.
