JFK conspiracy theorists don’t normally converge on the New York Art, Antique and Jewelry Show, but they will this weekend.

Item No. 30-4201 for sale at the show is, after all, the so-called Garrison Files — a collection of items from the only trial to examine whether a conspiracy killed President John F. Kennedy in 1963.

The Garrison Files are priced at $168,500 and feature two of the only seven known copies of the famous Zapruder film — the 8mm video that captured JFK’s assassination in Dallas.

Bill Rau of New Orleans’ MS Rau Antiques told The Post he purchased the files less than a month ago from the daughter of the lead investigator for Jim Garrison, the former hard-charging New Orleans district attorney who drew worldwide attention by asserting a conspiracy and a coverup in JFK’s assassination.

Garrison believed anti-Communist and anti-Castro extremists in the CIA were behind the murder — and in 1969 he prosecuted local businessman Clay Shaw as a co-conspirator with Lee Harvey Oswald.

After 34 days of testimony, the jury took less than an hour to acquit Shaw.

But suspicions that Oswald did not act alone have never gone away. They erupted with a vengeance after the release of Oliver Stone’s 1991 film, “JFK,” in which Kevin Costner played Garrison.

“We deal in cool, and this is one of the coolest things that has ever happened to us,” says Rau, a third-generation antiques dealer whose New Orleans store has been a French Quarter landmark for 100-plus years.

The daughter of Garrison’s lead investigator, whose family had known the Raus for generations and owned the papers and video for decades, decided to unload the collection recently before moving to England.
