Yup, stuff I didn't know. Not that I knew much about Transformers, only what I learned from having a son who loved Transformers.
But it does it's job in introducing the story of how Transformers came from Japan to the United States and the multiple transformations they went through in storyline, mediums, and focus. About 2/3 of the way through it got a little too detailed for a Who HQ book I thought, but it rallied at the end and I liked the profile of the World Record holder for the most Transformers memorabilia.
