Vintage large-scale wall chart of the anatomy of the "Vipera berus" (Reptilia, Ophidia II). Lithograph on two sheets of paper, mounted on canvas. Bright colors, some creasing, slight discoloration, cracks at centre top, protective tape at the edges, but overall good vintage condition considering its age and use. Author and illustrator was Prof. Dr. Paul Pfurtscheller. Pfurtscheller (1855 - 1927) produced a series of 39 "Zoologische Wandtafeln" (zoological wall plates) to be used for higher educational purposes. Although he was a modest high school teacher by training he gained recognition by the scientific community worldwide for this outstanding work. The viper is "Plate 34" in the series. The Pfurtscheller wall charts were first published in Vienna, Austria, in 1902, by 'A. Pichler's Witwe & Sohn'. This item was published by Dutch company 'Martinus Nijhoff' presumably circa 1929. Later editions were also published by Dutch company 'Martinus Nijhoff' until 1953. This item was pubished by Martinus Nijhoff in 1926. It is one of the very early lithographed editions, whereas later editions used offset-printing.
