Now, that drawing has been auctioned off for a reported $16,000.
The famous picture shows Kate's character, Rose, seductively lying on a couch wearing nothing but the iconic blue diamond necklace.
In the film, DiCaprio's character, Jack, was the artist, but in real life, it was actually Oscar winning director James Cameron who sketched the image.
The sketch was sold to the highest bidder at Premiere Props' memorabilia auction over the weekend.
A spokesperson for the firm said: "This is a wonderful piece of memorabilia (from) one the biggest grossing films of all time."
BTW: The Oscar winning Winslet can currently be seen in HBO's epic mini-series Mildred Pierce.
