The 40-square-inch Shot Sage Blue Marilyn, one of dozens of images of Monroe made by the artist in the 1960s, will go on sale in New York this May, the auction house announced on Monday.

Using a technique called silkscreening, which duplicates images on paper or canvas using a layer of fine-meshed silk as a stencil, he began producing them in 1962, shortly after Monroe’s death. As with images of other famous personalities, including Elvis Presley and Chinese leader Mao Zedong, the pop artist has created many versions of Monroe’s portrait in various colors and configurations.
In 1964, he developed a “better and more labor-intensive” new process that Christie’s said was “at odds with the mass production for which he was best known.” That same year, he used it to create a limited number of portraits—a rare group of works to which Shot Sage Blue Marilyn belongs—before abandoning the technique.

In the meantime, Shot Sage Blue Marilyn was owned by a string of famous gallery owners and collectors before it was bought by the late Swiss art dealer Thomas Ammann. He is up for auction by the Thomas and Doris Ammann Foundation in Zurich, a charity set up on his (and his sister’s) behalf that will use the proceeds to fund health and education programs for children around the world, according to a press release.

Described by Christie’s as “one of the rarest and most outstanding images in existence”, the portrait has been exhibited in galleries including the Guggenheim Museum in New York, the Pompidou Center in Paris and London’s Tate Modern.
“Along with Botticelli’s The Birth of Venus, da Vinci’s Mona Lisa and Picasso’s Avignon Girls, Warhol’s Marilyn is unquestionably one of the greatest paintings of all time,” he added, “and it’s once in a generation the opportunity to publicly present this masterpiece is up for auction.
