Biology:Swedish Master Series

Swedish Master Series (Swedish Master-serien or Mästar-serien) is a set of hockey cards produced by a Swedish company between 1969 and 1971. At least two sets were produced and distributed in Europe. The first set was for the 1969-70 hockey season and the second set was for the 1970-71 season. Both sets included players from Swedish teams and national teams from other countries. Ken Dryden was featured in both sets prior to his debut in the National Hockey League.
