Here is an interesting find: A Spalding display promoting their “encore” line of tennis balls. The encore balls were advertised as “extra long life” and had the an unusual characteristic – colored seams for instant identification. This rack was probably used in a tennis pro shop, or counter display in a sporting goods store. One dozen cans could be placed in the rack section, and as one can was removed from the front, another rolled forward to take its place.
