EXCELLENT!!! That IS the famous never before seen until now "Atlanta Child Murders" - "Zodiac" letter! It was postmarked "Atlanta, GA March 8, 1981". I wrote about it before: I am doing a FOIA request for this letter mentioned in the FBI Atlanta Child Murders file. It says it is from the Zodiac, and the FBI handwriting analyst could not say it was from Zodiac, but he could NOT exclude it as being from Zodiac. All we know is it starts: "Hello its me. Haven't you..." Another letter is this time frame, perhaps also from this "Zodiac", was a demand that the Washington Post classified run this ad as a secret message: DANIEL PLEASE CALL HOME At almost the same time, a message was sent in the same way as the Zodiac Sacramento Cancer and Leo cards - in a prepaid envelope. This letter was treated as credible, there are 10 pages on it in the files, and 3 kids were killed that March in Atlanta. Only three cities got this insert for classic model cars that the message came in - Harrisburg PA, Chicago IL and Long Beach FLA.
