British Design Classics – Available from Tuesday 13th January 2009

Your 2009 Special Stamp collection starts here.

We always like to start the year with a classic and this year we’re launching our Special Stamp programme with ten, in one very special issue – British Design Classics.

Britain has produced some of the world’s most iconic design work of the 20th Century and to help us select which icons to choose we gathered together a panel of experts from the world of design to help us make the final cut.

From the distinctive lines of R J Mitchell’s Spitfire fighter and the stylish chic of Mary Quant’s daring mini skirt to the calm of the Penguin Books jacket and the practicality of Robin Day’s Polypropylene chair.

But there’s one brilliant design that remains close to millions of people’s hearts - the Mini. Fifty years ago, in 1959, the first Minis rolled off the production lines at the British Motor Corporation’s plants at Longbridge, Birmingham and Cowley in Oxford.

Designed by Sir Alec Issigonis, the revolutionary small car remained in production until 2000 and is the most popular British designed and built car ever. Not only that but its stylish design made it a hit with the trend setters of the swinging sixties with everyone from John Lennon and Marianne Faithfull to Peter Sellers and Steve McQueen owning one.
