Arno Petersen with mini Stanley Cups made by C. P. Petersen & Sons
Arno engraved (stamped) the Stanley Cup after his father Carl Poul Petersen passed away in 1977, until 1979, after which the family closed the silversmith shop. When C. P. Petersen & Sons closed, the NHL contract was up for bids. Boffay Ltd. bought the Petersen stock and continued the trophies trade. The cup is now engraved by Louise St. Jacques
Arno spent his working life as a silversmith craftsman with C.P. Petersen & Sons, following in his fathers footsteps, and was instrumental in creating many of the trophies used in the NHL, including the Conn Smythe Trophy (Toronto Maple Leafs founder), which is a trophy with an image of the Maple Leaf Gardens building in Toronto, Ontario commissioned by Harold Ballard (1904-1990), the late owner of the team, the Hart Memorial Trophy and the Bill Masterton Memorial Trophy.
