Christie’s has announced its highest value single-owner collection ever – which is estimated to sell for up to £126.7 million.

Monsoon: The Peter Simon Collection comprises nearly 200 works from the personal collection of the British businessman, who founded fashion retailer Monsoon.

The estimate is around £86.5 million to £126.7 million and it will be offered in three dedicated sales during Frieze week in October.

It represents the highest value single-owner collection offered to date at Christie’s London in a single marquee week.

Pieces included in the sale come from artists including Francis Bacon, Piet Mondrian, Joan Miró, Andy Warhol, Pablo Picasso and Hurvin Anderson among others.

The collection includes two paintings from distinct stages of Bacon’s career – 1978’s Figure in Movement and Study for a Figure, which is estimated to have been painted around 1945.

The first is expected to sell for between £14 million and £18 million while the second is expected to sell for between £4 million and £6 million.

There are also modernist works from Ben Nicholson and Barbara Hepworth – including Nicholson’s 1934 (relief), hand-carved from a single piece of wood and expected to fetch between £1 million and £2 million.

Hepworth’s 1948 work on paper, The Hands and The Arm, could reach an estimated £250,000.

Other important artists from the School of London, Frank Auerbach and Leon Kossoff, are also offered in the sale – Study of Primrose Hill and Christ Church, Stormy Day, Summer.

Those pieces are estimated to sell for up to £3 million and £600,000, respectively.

The auction house has said The Peter Simon Collection “stands as one of Britain’s foremost modern and contemporary art collections”.

Speaking about his collection, Simon said: “In the early days at Monsoon I would sit with fashion and textile designers sifting portfolio after portfolio to select works on paper which we would convert onto fabric for clothing collections.

“A critical part of the DNA of Monsoon is the colours and the prints. In retrospect, I realise this work happily honed an ability to recognise good composition with colour balance – having developed an eye for a good print, I find it helpful to zero in on the best combination of colour and composition in a picture.

“I focused on the British artists who first attracted me, as well as more contemporary artists then emerging on the scene, always aiming to build links and foster dialogue across different worlds.

“It gives me great pleasure to now offer part of my collection to others, freeing my mind and my walls to start in a new direction.

“I hope these works can thrill their new owners and enhance their lives in the way they have done for me.”

Other pieces in the collection include Piet Mondrian’s 1935 Composition A, with Double Line and Yellow, Joan Miro’s 1925 Peinture (Les amants – Adam et Eve, Fernand Leger’s Le Siphon, and Pablo Picasso’s Crâne, lampe, poireaux, pichet , painted just days before Europe celebrated the end of the Second World War.

That piece was last seen in a public exhibition more than 25 years ago.

Also up for sale are Bridget Riley’s Streak 2, Alighiero Boetti’s Mappa, Willem de Kooning Untitled from 1984, Jeff Koons’ Baroque Egg with Bow (Blue/Turquoise), and Andy Warhol’s Diamond Dust Shoes.

Hurvin Anderson’s Last House – which was included in the artist’s 2017 Turner Prize exhibition and his 2026 Tate retrospective – is expected to sell for up to £3 million.

Christie’s post war and contemporary art specialist Joseph Braka called the collection “one of the finest and boldest ever assembled in the United Kingdom”.

“Whilst deeply rooted in the masters of 20th century British painting, the collection was one of the first in the country to evolve and encompass art from across the globe,” he said.

“Stemming from an instinctive understanding of colour and line, honed by forming and running Monsoon since 1973, it stands as an emblem of Peter Simon’s own journey: pioneering, borderless, vibrant and of the highest quality.

“The collection shows us all that one does not have to be cornered into one genre, one period, one movement, one place.”

Monsoon: The Peter Simon Collection will be presented in a special exhibition, open to all, taking over the galleries at Christie’s London from September 26 until October 1.

The auction will take place from online from October 1-20, with the evening sale on October 14 and the day sale to be held on October 15.
