London Transport, and its antecedents had a design culture of remarkable richness in the interwar years. Think of Charles Holden's station designs, the lettering of Edward Johnston, the Underground map of Harry Beck, and the posters of Edward McKnight Kauffer. Less well known are the black and white illustrations made for press advertising, although at the time they must have achieved a wider penetration than all other forms of design and publicity, since they were seen in daily papers even by people whose life or work only rarely took them to London. They therefore deserve study and celebration, and of the many artists who illustrated them, Edward Bawden and Eric Ravilious seem to stand out as having qualities that go beyond the period charm shown by others.
