I bought this 25 years ago when I was in college. I thought, "Hey, this will be a fun side-textbook." Then I never read it.
Like many folks my age, I was introduced to Art Deco by Batman: The Animated Series. I had never seen "Metropolis." I just liked the sheen and the bold, soaring lines.
The vast majority of this book is pictures. (As it should be.) The text can easily be read through in a day. The enjoyment depends entirely on how much you like taking in photo stills. By the end, I had a list of movies that I wanted to watch, but I will probably give the book away.
If you know the movies of the 20s and 30s, then you are all set. If you were born half a century too late, then you will have some catching up to do.
From my limited knowledge, it was a fine overview of a bygone era.
