This book of Norman Rockwell's work is a fascinating look into the typical/almost idealistic life of everyday embarrassing/comical/poignant situations which do commonly occur.
If you can only have one Norman Rockwell book, look no further. This is the quintessential Norman Rockwell. You can spend hours and hours looking at the illustrations and still not fully grasp all the subtle nuances - like the cameo paintings within the painting; the reflections in the mirror; the advertisements in the folded newspapers; and so on.
