This is a collection of dates from the 15th Century on showing facts of historical importance. The pages were designed and drawn by graphic artists. There is a focus on scientific discoveries but also the arts and various happenings like the Woodstock music festival and moon landings in recent times. The colourful illustrations are often amusing and may refer to Mona Lisa or the Rhino woodcut, may be a spiral of words or a play on words.
The book is designed with a plain hard cover and without a spine. It is an entertaining dip-into read and the author who compiled the lists got it produced by herself, which must all have been highly entertaining for her.
