Vintage large-scale wall chart of the anatomy of the cockroach "pustules vulgaris" (Blattaeformea.) 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 very 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 cockroach is "Plate 39" in the series. The Pfurtscheller wall charts were first published in Vienna, Austria, in 1902, by 'A. Pichler's Witwe & Sohn'. Later editions were also published by Dutch company 'Martinus Nijhoff' until 1953. This item was published by Dutch company 'Martinus Nijhoff' presumably, circa 1929. It is one of the very early lithographed editions, whereas later editions used offset-printing.
