In the opinion of this international hockey junkie, the two best All Star breaks didn't feature an All Star game at all. In 1979 the NHL All Stars played a three game series against the Soviet National team in a "showdown of the century" called the 1979 Challenge Cup. In 1987 they did the same in a two game extravaganza known as Rendez Vous '87.
Seeing as this is a hockey history website, I have featured each of these two tournaments significantly for the upcoming All Star festivities. Features include video footage, original articles and personal memories. Just click on the following links: 1979 Challenge Cup and Rendez Vous '87.
