Lucio Fontana's La Fine de Dio has set a new artist record, at Sotheby's.
The lot led a sale of post-war Italian art in London on October 15 with a sale price of £15.9m ($24.7m).
That's a 21.3% increase on the artist's previous record, set at £13.1m ($20.2m) in 2013.
It's also a new record for a piece of post-war Italian art.
The work is a unique egg-shaped variant of his iconic "slash" paintings.
The sale also featured a work from Alberto Burri, whose Bianco Plastica 1 took second place with a £2.6m ($4m) final bid.
Alex Branczik, Sotheby's head of contemporary art in London, comments: "Over 10,000 visitors crowded our galleries for our Frieze Week exhibitions - and this excitement carried through into a packed saleroom.
"When we first introduced a dedicated Italian Sale to London in 1999, the entire sale made £5.2m, tonight we've seen a single work make three times this amount.
"The energy we saw in the room for both sales; the bidding from every corner of the globe; the appetite for both young and established artists - it all came together here in London tonight."
