I received this book as a gift for my birthday some time in the early 90s, I would have been 10 or thereabouts. Long before the era of iPads and easy entertainment books were my thing. I read this one over and over and even though I haven’t seen it since I left my childhood home 20 years ago, occasionally it will enter my thoughts just because I learned so much from it with its wide variety of topics and fun layouts and explanations.
