The collection, which includes works by some of the greatest artists of the 20th century, went under the hammer
in New York on March 31, following a tour of Hong Kong, Paris, London and Los Angeles.
Bacall, who died in August 2014
at the age of 89, first shot to international fame in 1944 with her first film, "To Have And Have Not
That was also when the husky-voiced starlet met her future husband, Humphrey Bogart.
At the recent 2015 Golden Globes, George Clooney paid tribute
to the silver screen queen in his award winning speech.
"I don't remember what awards Lauren Bacall won, I just remember her saying: 'You know how to whistle, don't you Steve. You just put your lips together and blow.'" said Clooney, referring to one of her most legendary lines from her first movie.
The 750-piece collection, which fetched a total of $3.64 million
, featured bronze sculptures, jewelry, and a number of decorative arts and paintings, which were sold at Bonhams auction house in New York.
"Her collection is truly a reflection of her extraordinary taste and remarkable life," said Jon King, Bonhams' vice president.
Among the 50 items highlighted in the auction preview were six bronze maquettes by Henry Moore
, Britain's greatest 20th century sculptor and one of Bacall's favorite artists, whom she developed a close relationship with. One of them
sold for close to $120,000.
Also for sale were some of Bacall's most loved jewelry pieces
, created by legendary French designer Jean Schlumberger
, most known for his work at Tiffany & Co.
A rose diamond camel brooch
by British jeweler Elizabeth Gage fetched $23,750 and was accompanied by the original drawing and correspondence from the designer, which shows the close-knit relationship Bacall had with Gage.
The wide-ranging collection was expected to appeal to a variety of collectors: fine arts and antiques dealers, fans of Lauren Bacall and Humphrey Bogart, as well as memorabilia enthusiasts.
Most of the items auctioned come from the apartment in New York's Dakota Building that she shared with her second husband, actor Jason Robards
, until 1969. But King said fans of Humphrey Bogart would have been pleased to know some of the items were also from their shared residence in Los Angeles.
King, who got to know Bacall in her late years, said the collection reflects the actress' eclectic taste, and there was only one principle she applied to collecting:
"Everything had to kind of speak to her, to catch her eye. She loved form, she loved texture, she loved color. And she loved mixing it all up. She said that when you walked into her house, what she liked was that it was never boring," King said.
"You could walk into the same room a hundred times, and see something new every time."
