How do you sell something nobody can see? Yves Klein had an answer in 1959: you sell it for gold and hand over a receipt. A book of those receipts is the headline lot at Doyle in New York today. On Thursday, 12 November 2026, at 11 a.m. local time, the auction house holds its Important Fine Art sale of 90 lots, featuring property from the collection of the late critic and curator Robert Pincus-Witten and his husband, the textile designer Leon Hecht.
A receipt as a work of art
For his Zones of Immaterial Pictorial Sensibility, Klein offered buyers empty “zones” of artistic sensibility in exchange for fine gold. The buyer received a receipt – and could either keep it or burn it in a ritual that, according to Klein’s rules, completed the transfer of the immaterial work. The book on offer, Series 5 from 1959, contains French-language receipts specifying 320 grams of fine gold; its cover carries nothing but the artist’s signature and his deep ultramarine blue. According to Artnet, the sale includes six works by Klein in total.
Few objects pose the questions of conceptual art more directly: what is the artwork here – the empty zone, the gold, the ritual or the piece of paper? And who owns what after the receipt has gone up in flames? Doyle calls the lot a rare opportunity to acquire a piece of a landmark work of conceptual art.
A collection built on friendship and conversation
The consignors’ story is remarkable in itself. Pincus-Witten and Hecht, both born in 1935, grew up on the same block in the Bronx and met in kindergarten. They reconnected as adults and stayed together for more than fifty years, until Pincus-Witten’s death in 2018.
Pincus-Witten was a long-time professor at Queens College and wrote for Artforum in the 1960s and 1970s; his 1971 essay on Eva Hesse helped shape and name the idea of post-Minimalism. Later he curated for Gagosian and directed exhibitions at C & M Arts. Hecht studied at Black Mountain College, mastered screen printing and ran Sun Fabrics, a Broadway loft that produced textiles for neckties. Their collecting followed a simple idea: buying the art of one’s own time is a way of taking part in its conversation.
Beyond the Klein
The couple’s property sits alongside works from other consignors by artists such as Odilon Redon, Camille Corot and Alexander Calder. Further items from the collection are scheduled for later Doyle sales, including jewellery on 13 November and rare books, autographs and maps on 24 November.
The result will be a small but telling data point in a busy November: while the big New York evening sales next week will be measured in tens of millions, today’s lot asks what a receipt for nothing is worth.
