DALLAS, TX.- Le Corbusier's Untitled, 1937, an important example of the artist's study of the line and the female form — personally gifted to Edith Milton, wife of architect Wallace Harrison — could sell for $30,000 in Heritage Auctions' 20th & 21st Century Design Auction March 31 in Dallas. The auction offers exceptional examples of how national and international architects, artists and furniture designers perceived two centuries of radical change.

"As the founding father of Purism, few artists could convey so much with a single line as Corbusier," said Frank Hettig, Director of Modern & Contemporary Art at Heritage. "Ironically, Corbusier inscribed the painting with friendship to Ms. Milton but his artistic falling out with Mr. Harrison forever changed their friendship as well as the look of the United Nations headquarters building in New York."

Harrison invited Corbusier as part of a team of international consultants as he began planning the United Nations headquarters in New York. Corbusier wanted the committee and meeting building to be a low, extended horizontal form. When Harrison dismissed the idea altogether and instilled a plan for a two-story building instead, Corbusier disaffected himself from the project and Harrison.

The auction includes accomplishments by artists such as legendary California woodworker Sam Maloof, whose handmade furniture resides in the collections of the Metropolitan Museum of Art as well as the Smithsonian American Art Museum; Rocker (No. 43), 1989 and stand as an eloquent combination of form and function (est. $30,000+).

Though best known for his paintings of California swimming pools, British artist David Hockney also worked with ceramics in his youth. Cat, circa 1955, is one of these rare early works and was made by the artist when he was just 18 years old. The piece offers a hint of the aesthetic that would influence British art for nearly five decades (est. $20,000+). A charming polychrome glazed earthenware dog bowl painted in 2010 by the artist, with the words "Food and Love," also appears in the sale (est. $5,000+).

Structure Ambigüe Cristal, 1971, by Yvaral (Jean-Pierre Vasarely) will be offered for the first time at public auction after spending the last 44 years in private collections in Canada and Dallas (est. $20,000+).

A selection of three artworks by Austrian artist Niki Kogelnik, an icon of Pop Art, includes variations on her blown glass heads: Ocean Head, circa 1995 (est. $15,000+); Night Head, circa 1994 (est. $15,000+), and Censorship Head, 1996, (est. $15,000+).

Untitled, 1984/2006 by Herbert Bayer, considered the last living member of the Bauhaus until his death in 1985, is a posthumous sculpture copyrighted in 1984 by Herbert Bayer and again by the Herbert Bayer Estate in 2006. It is abricated directly from the Herbert Bayer maquettes and authorized by the Bayer Estate in a finite edition of six (est. $12,000+).

Instantly recognizable metalwork design by Franz Hagenauer include Two Heads, circa 1950, and Pair of Heads, circa 1960, both by (est. $8,000+ each) and Untitled (pair of sconces), circa 1970-1979, (est. $6,000+).

The auction includes a special selection of furniture and objects by celebrated Chinese designers from the Zizaoshe Furniture Collective, founded in Beijing in 2002. The Collective incorporated gave voice to Chinese culture within design as seen in as three works from the 2012 Wood Series by Xue Wenjing, including Coat Rack, Chair, and Ottoman (est. $2,000+ each). The line-up includes Object # ET2-BP (two stools), 2012, an innovative pair of computer generated, hand-crafted stools from the digital lab of up and coming designer Zhang Zhoujie (est. $6,000+), and Song Tao's Rebecca (tea table), 2012, a stunning combination of antique elm and cast aluminum joints (est. $4,000+). All of the artworks featured in the auction were also featured in the exhibition DESIGN+ held Washington, DC last year.

Seven lots relating to the design and influence of legendary architect Frank Lloyd Wright includes Dining Table from the Arizona Biltmore Hotel, Phoenix, 1927 (est. $3,000+) — developed with artist Warren McArthur — and five lithographs from The Wasmuth Portfolio, 1910, of perspectives and drawings done at Wright's studio in Oak Park, Illinois.
