First edition. Signed by Bridget Riley. Publisher's original black and white card covers. Black and white photograph of the artist to inside cover, eight works reproduced in colour and thirty-nine in monochrome. A very good copy, the binding square and firm with some rubbing to the spine tips and a few marks (including a cup ring) to the covers. The contents are clean throughout and without previous owner's inscriptions or stamps.
Signed by Bridget Riley in blue ink on the title page, highly desirable thus.
