My 5-year-old daughter loved the "I Spy" series, and we got her a couple of these "Usborne 1001" things to spot books after she'd gone through (many times) all the I Spy books. She loves these as well. The drawings are colorful and detailed, typical Usborne. The searching is not too difficult, but just enough challenge for a 5-year-old. There are some instances when I can't find all the items. I really like these books and would buy more in the series.
