F. Ad. Richter began selling the first Anchor Stone puzzle in 1890, and the same puzzle is still being produced 120 years later. The first puzzle was the Chinese Tangram and it was so successful that Richter designed and produced four new puzzles within the next two years. His success was due to the attractive look and feel of the stones and by the beautiful graphics by the best German artists on the covers of the boxes and problem books.

The book is a journey of 120 years through the development of amazing puzzles during the turbulence of European history. It tells the stories of the puzzles and shows all of the Richter's puzzles and their many variations over the years, and it provides more than 650 problems for you to solve from 37 Anchor Stone Puzzles.
