The Bruins welcomed back a superstar on Tuesday night, as Tyler Seguin returned to the Garden for the first time since being traded to the Stars.

Seguin was shipped to Dallas over the summer, and while the unceremonious departure led to a blockbuster seven-player trade, it was far from the first time the B’s traded away one of their cornerstones. From Joe Thornton to Phil Kessel, the Bruins have dealt first-rounders, but one deal in 1975 included even more drama with the combination of fierce rivals, huge names and a deal that no one saw coming.

On Nov. 7, 1975,  Boston  traded center Phil Esposito and defenseman Carol Vadnais to the Rangers for defenseman Brad Park, center Jean Ratelle and defenseman Joe Zanussi in what would become one of the most monumental trades of the decade.

The shakeup changed the identity of both teams for years to come, but Ratelle and Park fit in mighty fine with the Bruins, both eventually making it into the Hall of Fame.
