Saco River Auction Co. in Biddeford is holding an auction Wednesday evening that includes a card depicting the Brooklyn Atlantics amateur baseball club.
The man told police he attended the Batman film in Saco, Maine, on Saturday with a loaded gun in his backpack and told authorities he was traveling to Derry, New Hampshire, to shoot a former employer.
About half a dozen people are expected to bid by phone, and at least five people have said they'll travel to the auction house to place bids, said Troy Thibodeau, manager and auctioneer at Saco River Auction.
