Fourth of July ca. 1900

This photo did not scan real well bit I am sure it was taken at the 4th of July picnic in Yorktown, Il in 1900. My grandmother is the little girl standing in front with her half sister Nellie standing behind her.
 My grandma has a fan ? or shaker ?in her hand with a man's photo on it- my guess the man is President Wiiliam McKinley
 See the little girl behind them sticking out her tongue?
