A gift of 130 works of major artists, mostly Modernists, will be given to the Los Angeles County Museum of Art, according museum’s officials on Wednesday.

The works include 20 works of Picasso that comprise 65 years of activity, 21 watercolors and paintings by Paul Klee and Wassily Kandisky, seven sculptures and a painting by Alberto Giacometti, and two versions of the “Bird in Space” by Constantin Brancusi, Los Angeles Times reports.

Janice and Henri Lazarof are the ones that will make the gift to the museum. They are longtime collectors and also Los Angeles residents.

Mr. Lazarof is a veteran composer born in Bulgaria in 1932, who was a professor at the UCLA’s music faculty from 1962 to 1987. His wife, Janice, daughter of S. Mark Taper late banker-philanthropist, is the president of the S. Mark Taper foundation. Their collection is the result of 25 years of assiduous work of collecting works of the imposing figures of the 20^th’s century art, like Georges Braque, Henri Matisse, Joan Miro and Henry Moore.

Although the value of the artworks wasn’t revealed by the museum, taking after recent auctions for similar works, collection’s worth can reach over $100 million.

Michael Govan, LACMA's director said: “It's a major deal to get this work in one fell swoop, at a time when the art market has made it nearly impossible for museums to purchase work of this quality. This significantly expands the modern collection, where we need help. We have major works and landmark things like the Robert Rifkind collection of German Expressionism, but we don't have the richness and depth of modern art that you expect of a museum of this scale. This gift doesn't complete the picture, but it adds a lot."

According to senior curator of modern art at the museum, Stephanie Barron, the LACM now owns from every work in the Lazarof collection a small percentage, and the rest of the share will be transferred in time.

The announcement was made by the museum two months before the opening of the Broad Contemporary Art Museum, which was designed by the architect Renzo Piano for the art collection of Eli Broad, the Los Angeles philanthropist and billionaire, the New York Time informs.

Eighty works from the Lazarof collection will be on display staring January 13. Lazarof’s collection will be put on display in three galleries in the Ahmanson Building.

Among the works of Picasso, Kandisky, Klee, and Giacometti the collection also includes two sculptures by Henry Moore and three Cubist canvases by Georges Braque.

The gift also includes Futurist work by Gaicomo Balla, the first one of its kind to ever be on display in the museum.

Barron said that works from artist who worked in Italy before the World War I “are incredibly rare, unless you were buying them in the ’40s and ’50s.”
