He plays with double meanings, visual riddles and, like Magritte, teaches us that “a pipe is not always a pipe.” Its pages show independent images - although related to each other - establishing a chained structure, so it can become a circular story.

Its pages are foldable, so that the first one with the next presents an illustration; but when opening the latter, another different figure is formed. Thus a game arises between what is seen and what is hidden, what seems like something but is transformed into something else... Added to this imaginative and surprising approach is a collection of easily recognizable illustrations that stand out for their descriptive nature.

Being a book for all ages, it is especially attractive for pre-readers and early readers, since it allows a free narration exercise while the little ones try to guess what drawings are hidden behind each page.

The result is that girls and boys identify the images, they are amazed and surprised - hence the title - when they discover the unknown part of each one, they learn the sequence and direction of narrative and visual reading, while developing imagination
