Le safran / 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 saffron crocus (crocus vemus), its cultivation and how the plant is harvested to produce a medicinal product. The colour image on the front shows its flower, seeds and stamens and it being dried by hand over burning coals by peasants. Liebig cards appeared in various languages. This set also advertises Oxo beef tea.
