“In a challenging workout for Where’s Waldo? fans a Canadian cartoonist offers 82 teeming scenes in pairs that are identical only at first glance … the figures and action are depicted with fine-lined exactitude, and there’s plenty of stage business and visual humor to keep even browsers uninterested in playing the intended game amused.” —Kirkus Reviews “Bùi's cartoon-like illustrations are visually attractive, and they humorously present a wide variety of indoor and outdoor scenarios…. Spot the Difference is a good gift…. Time spent during long car rides or being stuck indoors because of inclement weather will seem to pass more quickly by those questioningly engaged in Bùi's clever art.” —Recommended, CM Magazine “Spot the Difference by Tak Bui is a collection of search-and-finds challenging readers to compare pictures and find the differences. Each illustration is a rich mixture of witty scenes that invite storytelling to keep young readers intrigued.” — The Calgary Sun
