I'll confess that I should have read this a long, long time ago, and have had a copy of it that I purchased on a visit to Pooh Corner books (one of my childhood haunts) floating around in my car for months. I figured there was no time more appropriate than an impending visit to the Metropolitan Museum of Art to get it in gear! This would be a superb read-aloud for elementary classes (where it already has a well-established home), and affords all kinds of teaching points from art appreciation to research skills. An afterword in my copy explains how much of the museum has changed in the years since it was written, so I didn't get to see many of the big things that the book depicts, but still, it was fun to visit the museum right after reading it.
