The list reflects a comparatively high turnover with 28 dealers who exhibited last year not standing in the 2017 event at the Royal Hospital Chelsea, London, from June 29-July 5.
Among the dealers not returning are antiquities specialist Charles Ede, medievalist Sam Fogg, Old Master dealer Lampronti Gallery and works on paper Stephen Ongpin Fine Art.
Some of the 26 new exhibitors announced include modern and contemporary art specialist Hazlitt Holland-Hibbert, Gregg Baker Asian Art, rare books dealer Librairie Camille Sourget and Old Masters specialist Derek Johns. EH Manners, formerly a regular at Art Antiques London event, also joins Masterpiece this year.
Returners include Agnews, Hélène Bailly Gallery, Blairman & Sons, Butchoff Antiques, Dutko Gallery, The Fine Art Society, Richard Green, Osborne Samuel and Peter Harrington.
Alongside the Olympia fair, Masterpiece is one of only two major London summer fairs in 2017 following the closure of Art Antiques London.
It is the first Masterpiece to take place following the launch of TEFAF New York Spring where some former exhibitors, such as Charles Ede, have taken stands.
Nazy Vassegh, who joined the fair as CEO in 2013, resigned at the end of 2016 and chairman Philip Hewat-Jaboor heads the fair this year.
