Keen-eyed John Merritt looks carefully at the Principia Discordia noted by Jesse Walker (see Friday's post) and notices something interesting:
"Reference copy, JFK Collection HSCA (RG 233)" along right edge of each page. Thornley served w/ Lee Harvey Oswald in USMC.
This apparently refers to the files of the House Select Committee on Assassinations, from the John F. Kennedy Assassination Records in the National Archives.
Doesn't this sound like something from the pages of ILLUMINATUS?
