 Also the Cup underwent several minor alterations, namely the retirement of the collar in 1963 and the bowl in 1969 in favor of duplicates because the originals became too brittle.After the bands were finally all filled, the top band of the large barrel, with the 1927–28 to 1939–40 champions, was taken to the Hockey Hall of Fame, and a new blank band was introduced at the bottom so the size of the Stanley Cup would not grow further.One year later, the shoulder collar listing the names of the previous winners was also filled to capacity, but it was decided to keep it on the trophy, unchanged in perpetuity.
