"On This Day is a history book with a difference. From January 1st to December 31st you will travel back in time and discover the weird and wonderful things that happened around the world on every day of the year. From a close encounter with Halley's Comet on April 1, 374, to the introduction of Dolly the Sheep, the world's first cloned mammal, on February 21, 1996, there is something incredible to learn on every page. Unlike other day-by-day history books, On This Day uses quirky graphics and funky illustrations to turn back time and bring the past of each day back to life. No matter what your interests are, this visual feast of a book brings together an incredibly diverse range of events, all of them united by the day they share." -- Amazon.
