Douglas Cockerell & Son of Grantchester produced some of the most beautiful marbled papers of the last century before the company closed in 1987 following the death of Sydney 'Sandy' Cockerell, their master marbler. The peacock pattern above illustrates the type of effect he achieved with the process, which was captured in this mesmerising video made in 1970 by the Bedfordshire Record Office. Cockerell marbled papers can be seen in the extensive collection of decorative papers held by the University of Washington.
