During their existence there were a few years when Parkhurst did not make hockey cards, possibly because hockey cards wsere not yet as popular as the other big sports in the US. Decades later Parkhurst went back to their archives from the period and came up with the players and designs they might have used in those years, and they came up with a "missing link" set of cards in the style they would have used had they published in those years. The card in this ad is one of the cards from the "missing link" 1966-67 season featuring NHL legends Bobby Hull and Frank Mahovlich on a duo all-star card. An excellent design with TWO NHL legends on one card. 

Bobby Hull and Frank Mahovlich are celebrated as two of the greatest players in NHL history, each leaving an indelible mark on the sport. Hull, known as "The Golden Jet," revolutionized hockey with his blazing speed, powerful slapshot, and innovative curved stick blade, setting records like being the first NHL player to score over 50 goals in a season. Mahovlich, nicknamed "The Big M," was a dominant force with his smooth skating and explosive scoring ability, winning six Stanley Cups and setting a playoff scoring record in 1971. Their rivalry highlighted the era, with Hull's offensive brilliance often clashing with Mahovlich's all-around prowess. As hockey expert Frank Mahovlich himself remarked about Hull, "Give him a puck, a stick, and a pair of skates, and put him on your team—do you need a new concept?" This quote underscores the transformative impact both players had on the game.
