The artwork on these charts dates back to the 1890s, when they were used as classroom illustrations. They have been since too, with the charts produced by the same company since the 1950s and using the same printing techniques today as were used in the '50s.
They are available for your home now, in a choice of sizes and in a two ranges – zoology and botanical. You can see an illustration from both here. Each is paper mounted in canvas and fitted with wooden rods, nylon cord and a fabric tie.
Prices start at £59.
