Found - a loose bookplate by Paul Nash for the industrialist and art collector Samuel Courtauld. Produced around 1930, it measures a sizeable 13 by 9.5 cms, probably intended mainly for art books and livres d'artistes. The writer and broadcaster Lance Sieveking writes in his autobiography The Eye of the Beholder (Hulton Press, London, 1957) -'Sam Courtauld and Paul met at a dinner party I gave at Number 15 The Street, and Courtauld persuaded Paul to design a book plate for him. The result was one of the most charming he ever made.' The engraving is said to be the only one initialled by Paul Nash on the block. The bookplate is quite scarce as, presumably, it is mostly found in books held at the Courtauld Institute; few have entered the used book trade.
The woodcut is British Surrealist in style with an echo of Cubism and Vorticism - both movements had earlier attracted Nash. Samuel Courtauld's family fortune came from the textile industry (rayon), hence the bobbin and threads. The French flag refers to the origins of the name Courtauld, a French Huguenot family whose early descendant was the celebrated goldsmith Augustine Courtauld. The Courtauld textile industry was based in Braintree and Halstead in Essex. The view through the frame shows what appears to be a Martello Tower - these are closely associated with the East Anglian Coast.
