The foldable cone includes first and second side panels that are tapered in the upward direction, each side panel having an outer surface and an inner surface, a lower edge, an upper edge, and opposing side edges. In addition, finger placement indicia may be provided, preferably on the cover of the baseball, to indicate a proper finger placement orientation for one or more baseball pitches. The signature lifting device has an inhibit position where the second signature follows a path, the path bypassing the first location so that the gripper bypasses the second signature.
