Récréations mathématiques
A mathematical recreations book by Édouard Lucas, Henry Delannoy, Charles Laisant and Émile Lemoine, published in Paris by Gauthier-Villars in 1883 for readers interested in puzzles and geometry. Its pictures are plain line diagrams of geometric figures, with lettered points, straight construction lines and figure labels such as Fig. 9, offering a designer a clean, precise vocabulary of technical schematic drawing.
