Movie lovers will NEVER LET GO of this purchase, as it is the very ticket that Jack Dawson used to board the Titanic in the movie by the same name.

The ticket appeared in the 1997 box office smash and was used by Leonardo DiCaprio’s character to board the ill-fated vessel.

But it can now be yours for $1500 – as it’s going under the hammer in a celebrity mega-auction that will feature sales tied to Elvis, Marilyn Monroe, JFK, Michael Jackson and Whitney Houston.

A passenger boarding the Titanic with a third class ticket would have likely paid just £3 for the voyage in 1912 – roughly £240 in modern money.

And even though the ticket was used by Jack Dawson to board the ship, the ticket is printed in the name of Olaf Gunderson – who Jack won the ticket from in the film.

And bizarrely, due to a quirk in the filming process, this ticket is actually printed BACKWARDS – making the details difficult to read.

In order to film the departure scene from Southampton which, in real life, was appropriately done from the port side, Cameron filmed the starboard side and then “flopped” the film in the lab.

Consequently, many notices, signs, and props were printed as mirror images so that the film could be “reversed”.

Overseen by GWS Auctions and running this weekend – November 11, 2017 – the “Famous Music and Hollywood Icons Historical Occasion” already has some of its 150-plus items valued in the millions – including Whitney Houston’s piano and Elvis’ private jet.

The King of Rock n Roll’s lots have received much media attention in recent weeks – mainly because they include such personal items.

Included are a childhood home that Elvis lived in and a trailer that he and his wife purchased for one of their ranches.

Brigette Krus of GWS Auctions said: “We have notarized affidavits of authenticity on many of the Presley items up for auction provided to us by the Presley family, including Elvis Presley Enterprises, Charlene Presley and Patsy Anderson Presley, a former 22-year employee of Graceland, as well as other credible sources.”

Cars happen to make up a large part of the auctions, with vehicles belonging to Elvis, Anna Nicole Smith and Hugh Hefner also set to hit the blocks.

The auction will take place at 10 AM PST.
