The basic red Black Hawks sweater with the indian head logo first came into being back in 1955-56. It began to evolve almost immediately with changes to the secondary logo size and placement, changes to the main crest, changes to the number of sleeve stripes, changes in the style of collar, the addition of black trim around the white numbers until arriving at today's featured style in 1973-74 plus the addition of names on the back in 1977-78.
Bonus jersey: Today's bonus jersey is a 1973-74 Pittsburgh Penguins J. Bob "Battleship" Kelly jersey. This jersey was worn for only one season, as the Penguins darkened this jersey from it's original shade of powder blue to a medium blue for one season prior to changing to a all new, more modern striping template the following year.
