Penguin Design Award

See the 2008 Design Award Winners here.

The first Penguin paperbacks appeared in the summer of 1935 revolutionising the publishing industry and becoming an integral part of British culture and design history. The development of Penguin covers runs parallel to the emergence of graphic design as a profession and, under a long line of talented and creative designers, the design of Penguin books has evolved and progressed.
