Earliest PZH catalogues
There are no known surviving catalogues for the first ten years of PZH production. The earliest catalogue we know is dated 1909, and it is most likely it was issued in late 1908 for the year 1909. Although this website does not cover the later years in any detail the later catalogues are too useful not to share. The dating of these is a matter of debate, so the names of the files indicate the approximate year.
