The Art of Instruction, Plant and Animal Anatomy Prints

Wall charts were first introduced in primary schools and would quickly find their way into high schools and universities. These wall charts became important teaching aids as populations increased and the numbers of students increased with it making circulating picture books, loose engravings and biological specimens impractical. According to Katrien Van der Schueren, author of The Art of Instruction, these educational wall charts originated in Germany around 1820. During the decade between 1990 and 1890 German printers alone published more than twenty thousand distinct charts that were sold and distributed around the world.
