From the Memory of the Netherlands comes 'The Art of Knowledge: Educational Botanical Wall Charts 1870-1960'.
"In the course of the last century and a half, large colour representations of plants and parts of plants were used to illustrate lectures on botany: the so-called educational wall charts. They give an impression of the knowledge, research and academical education in the field of botany in the Netherlands during the years 1870-1960.There are hundreds in the database and all the initial pages are in english. ['groot'=Large.]
Drawing on the huge collections of the Universities of Groningen, Amsterdam, Utrecht, Delft and Wageningen, totalling some 2,300 printed and handmade wall charts, a selection has been made for the Memory of the Netherlands."
