It Keeps Its Shape, It Gives Satisfaction, It is Guaranteed -- October 8, 2014

I am a little confused by this ad for the Reach Ball from the 1898 Spalding Guild.  "Adopted by the American Association."  I thought the major league American Association went out of business in 1891 and the minor league American Association didn't start until 1902.  Perhaps AJ Reach kept the name in its advertising after the league was gone.
