Collection to be auctioned includes rare Bert Corbeau hockey card MONTREAL, Oct. 8 (UPI) -- A Montreal-area auction house said a collection of hockey cards including the so-called Holy Grail of the hobby is the world's greatest hockey card collection. Marc Juteau, president of the sports memorabilia dealer Classic Auctions and organizer of the sale, said Simon Bourque of Quebec City is selling off a collection of hockey trading cards that includes "every single set ever produced between 1910 and 1942," Postmedia News reported Tuesday. Juteau, who described the sale items as the greatest collection of vintage hockey cards ever assembled, said the cards are in "unbelievable" condition and include the "Holy Grail" of hockey card collecting, a 1923-24 card featuring Bert Corbeau of the Toronto St. Patricks. He said the Corbeau card is especially rare because an Ontario candy company "short-printed" his card to keep too many children from collecting the entire set of 40 cards and winning a set of skates. Bourque said he decided to sell his collection when he decided it was complete. "There's no more challenge for me, because I think I have the best," he said. It's like, the job is done. Juteau said the haul is expected to bring in millions of dollars.
