Of course, nobody knows or could know with certainty, who the author of this postcard is. In other words, this code is open to subjective interpretation and no solution, despite the belief of the code-cracker, has been universally accepted. But here, I am not going to tackle the celebrity cypher from the angle of cryptology, because not only do I have a basic knowledge of ciphers, but also, the mere fact that so many people of greater ability than me have come to wildly different conclusions, is evidence of a code that is malleable. Some of these solutions can be found on Ricardo Gomez's Project MK-Zodiac site. Many people have put forward solutions to the celebrity cypher including the website and Rubislaw32 (a regular contributor to this site). There is little to prove this notion one way or another, but if somebody was mimicking the Zodiac Killer, one might expect the wording on the card to equally mimic previous correspondence, in particular, phrases he used with respect to his codes and ciphers.

Bearing in mind the 408 cipher mailed to the San Francisco Chronicle, San Francisco Examiner and Vallejo Times-Herald on July 31st 1969, many have pondered whether this postcard was mailed by the Bay Area murderer. On September 25th 1990 somebody mailed the celebrity cypher to the Vallejo Times-Herald approximately three months before the 1990 'Eureka' card, often associated with the Zodiac Killer. The characters in the cryptograms were deliberately spaced into separate words, as shown on the right. The reader had to identify the person and quote from the encoded text. He would create six celebrity ciphers a week featuring famous quotes from well-known people, past and present. Luis Campos, born in Santiago, Dominican Republic is an inventor, poet and cryptographer who created puzzles and ciphers for the United Features Syndicate of New York, beginning in 1983.
