Book pattern papers and covers were a speciality of the English designer Enid Marx RDI (1902 - 1998) although it was not the only string to her bow. Marx, a distant cousin of the Karl, was a sought after designer and artist and she was commissioned in the 1930s by London Transport to design several of the moquette seating fabric for passenger seats. These covers, worked up from both line block designs and wood engraved patterns were for Chatto & Windus's Zodiac Books - a sort of 'Penguin Book' series they published and date from c1949.
