Kupka’s factory job

THE Mira Jacob Collection sale at Bailly-Pommery-Voutier & Sotheby's (23.92 - 14.35% buyer's premium) included a smattering of drawings and watercolours by artists outside the dealer’s sphere of influence – from a small Picasso ink sketch of a Glass and Jar, bought in at €44,000, to a Degas pencil portrait of Thérèse Degas, 11 x 8 1/2in (28 x 22cm), which sold at a quadruple-estimate €77,000 (£52,400).
