That was 15 times the estimate and topped KAWS’ own record sale of US$2.7 million from last November, Artnet News reported.

“The auction room suddenly got a lot hipper, with all these cool millennial buyers in hoodies,” Edie Hu, art advisory specialist at Citi Private Bank in Hong Kong, told Bloomberg.

The piece was sold as part of a 33-item lot by Japanese collector Tomoaki Nagao, better known as NIGO, through a listing called NIGOLDENEYE Vol. 1.

The KAWS ALBUM is a parody of the cover of The Beatles’ 1967 album, Sgt Pepper's Lonely Hearts Club Band, featuring a variety of characters from the American cartoon series The Simpsons, replete with KAWS’ signature crosses for eyes.

Sotheby’s described the piece as a “rich and complex composition [that] shows the epitome of KAWS’ subversive wit, prescient vision and affectionate irreverence for our times, manifesting as an iconic apotheosis of KAWS’s entire artistic and cultural lexicon”.

KAWS is a former street artist now in his 40s, whose work received major interest from Hong Kong bidders.

Another piece, UNTITLED (KIMPSONS #3), which was sold for US$2.6 million, was bought by a “young Chinese buyer with a short back and sides haircut, who was wearing a green army camouflage jacket”, Bloomberg said.

The work, which depicts the Simpson family sprawled unconscious on their settee, also features the artist’s signature crosses for eyes.
