Melchior’s cult sci-fi The Angry Red Planet is one of the most imaginative space adventures of the 1950s, featuring the surreal “Cinemagic” technique that brought its bizarre Martian creatures to life. The UK quad is by far one of the rarest formats for this title, with very few surviving examples, and its striking imagery of the giant alien dominating the Martian landscape makes it especially desirable for collectors of vintage science fiction.
