Batman: A Celebration of 75 Years makes a fascinating read for anyone not too familiar with the history of the comic book character but still interested in how Batman got to where he is today. It's fascinating to compare and contrast the storytelling/narrative style of the old comics with the new.
However, I'm not sure I could recommend this to everyone - the over reliance on narrator boxes in the older material makes them very difficult to really get into and enjoy. Modern writing and drawing have really helped to push the art forward.
The book's well bound in a high gloss hard back with a striking dust cover design (pictured). The paper quality also feels great to touch. There's a lot of material to read through - all arranged in chronological order with occasional forwards to put the stories into the context of the time.
It's clearly aimed at a younger audience but doesn't talk down to the reader, so older fans (such as myself) can enjoy this too, if they're interested in getting a glimpse of how the Dark Knight has changed over the years.
I imagine that if you already have a good knowledge of Batman's history and have read the older stories contained in this book then there won't be much new for you here. The forwards are very cursory due to the book trying to hit such a wide audience. More specialist/in depth writing would have been a nice touch.
