"I drew Covent Garden’s Old Floral Hall, then at the corner of Covent Garden’s piazza, while designing the poster Visitors’ London for London Transport. The drawing is a study for it, where its interior can be glimpsed through the bottom arches. The finished poster design was reproduced in four-colour half-tone, so it could be painted in watercolour, the medium I’ve liked since boyhood. I painted it on a large but inconveniently circular dinner table in my Battersea flat, and felt proud to see it whenever I went on the tube."
