In August 1981, Maureen Garrett, Director of the Official Star Wars Fan Club, sent Guardian and several other fanzines a letter. The letter asserted Lucas Films Ltd. owned all the characters in the Star Wars universe.

The letter also alluded to the threat of possible litigation if this problem was not corrected. (email@example.com, Langley )
