Le camphrier / Compagnie Liebig.

One of a series of cards (sent in sets of 6 in exchange for coupons from jars of Liebig's 'Véritable extrait de Viande Liebig' or Extractum Carnis Liebig). This one describes the camphor plant (cinnamomum camphora), its cultivation and how the plant is refined to produce a medicinal product. The colour image on the front shows its flowers and leaves and it's distillation by hand in vats by peasants in Japan. Liebig cards appeared in various languages. This set also advertises Oxo beef tea.
