This is an original antique Victorian Era Advertising Trade Card.  This card advertises for the "Centennial Fanning Mill" made by S. Freeman and Sons of Racine, Wisconsin.   Front cover features young girl in blue bonnet with basket of roses.  Card is not dated, but I assume the mill was first made in 1876, and legend on back refers to 15 years in the field ...... So about 1891.  Card measures 3" x 5". and is in very good used condition.  .
