The gigantic archway near the West entrance to Coors Field is a sculpture entitled, "The Evolution of the Ball".  And is an ensamble artwork, headed up by artist Lonnie Hanzon. Rose's part was to create, out of terra cotta, the 108 balls, in nine different sizes. The balls were designed with themes  ranging from a dung beetle ball, to a Rockies baseball. Along the way, such themes as the debutante ball and Lucille Ball are explored. All the balls are well annotated at the base and it is well worth a stop, for a few minutes, and a few laughs. The piece was installed just before the Rockies inaugural Coors Field season, in 1995.
