Lucie Félix, a very gifted young creator, invents a book of forms and activities for toddlers, a book based on manipulations and discoveries. The text is very brief and only contains action verbs. The forms are simple, the colour planes adapted for toddlers, who discover the pictures and have fun, going from one surprise to the other, detaching and putting back in the detachable pieces of the book. One thinks about Iela Mari's work for its simplicity and inventive spirit. This formidable object is also a book about contraries: appear / disappear, turn on / turn off, and at the end, to disperse and reunite. A fine book!
