William Tillyer has travelled the world over four decades making watercolours, this book is a record of that journey and of the artist's personal journey within the medium of watercolour. With 224 full colour illustrations this sumptuous book investigates the watercolours of William Tillyer. Two essays by the American poet and critic John Yau situate Tillyer's works within the English watercolour tradition and within the world of contemporary painting, while an interview with the artist provides some revealing insights into his working practice and personal philosophy.
