HEIM, Roger, R. Gordon WASSON and Albert HOFFMAN. Les Champignons Hallucinogens du Mexico: Etudes, Enthnologiques, Taxinomiques, Biologiques, Physiologiques et Echimques. Accompanied by HEIM, Roger. Nouvelles Investigations sur les Champignons Hallucinogens.

(Paris): Editions du Museum National d’Histoire Naturelle, 1958 and 1965/1966.  First edition.  Two volumes.  A total of 540 pages.  Illustrated with 48 plates, 23 of which are in colour, some by the pochoir process, and 96 text illustrations of which 19 are in colour.  Complete in two parts the volumes combine to become without doubt the greatest work ever published on the subject of the “magic mushroom” — indigenous to many countries but particularly associated with Mexico because of its documented religious usage there extending back to pre-Columbian times.  The plates, whether they are depicting ceremonial usage in remote village huts, ancient artefacts, or laboratory specimens of mushrooms are exceptionally beautiful.  Both volumes in at least very good condition in printed wrappers.  A very nice set of this important work covering nearing aspect of the history, cultivation and ceremonial use of psilocybe mushrooms.
