Exceptional empty display box from the 1956 Topps Baseball Buttons issue an extremely scarce 50-pin issue. Each box contained a five-cent pin plus a piece of bubblegum. The boxes today are extremely difficult to find. This example is extraordinary a fully-intact box with rare at the folds and some minor creasing the number "51" written lightly in ink on one of the closing flaps. Quite a difficult companion piece to an already-difficult issue.
