To answer McFly's question (although the product information already answers it), this is a collection of the first 5 Where's Wallys, crammed into a book that's about 15 x 19cm large, complete with handy elastic band. The detail in the pictures is just large enough to be visible to someone with good eyesight, and nothing seems to have been left out - even the checklists are included, in fold-out pages that also help to divide up the 5 volumes when the book is closed.
All in all, this is a fantastic compilation of some classic kid's books in a much more portable format. And for those who might be worried (based on the image) that this is actually a 'Where's Waldo?', it's not - it's Wally through and through!
