An excellent book, though it has some minor problems. As another reviewer has pointed out, there seems to be confusion between hyphens and dashes, rendering some sentences difficult, but this problem seems to be sorted towards the end of the book. Also, Dick Tracy is referred to as Dick Tracey, and Paul Gravett is rendered as Paul Gravatt in one instance, What's more, Tommy Walls is referred to as a blonde, which is feminine, instead of blond, which is masculine (at least in the UK). Another minor irk is that there are pages with several photos on them, but instead of a description being under each individual photo, the info is given separately in a footnote, which means one's eyes are jumping from photo to footnote (usually on the opposite page) as if watching a tennis match.
These minor problems aside, the book is a must have for all Dan Dare fans, although, to be honest, aside from the unseen strips, it's not that much different from its predecessor 'The Man Who Drew Tomorrow'. In fact, some of the illustrations from that volume are absent from this version, which is surprising as there is plenty room to accommodate them in four numbered blank pages at the back of the book.
