The description states:
“De Zwann” (The Swan) WINDMILL
An original Dutch Windmill, with a 200 year history, operates with full sails in the wind, grinding whole wheat flour. At the left of the gallery can be seen the capstan (hand winch) which rotates the cap to direct the winds into the wind. Higher than a 12 story building, it stands on a 36 acre island surrounded by quaint gardens and authentic Dutch architecture.
–Since the windmill was installed in 1965, the card undoubtedly dates from near that time.
