Commuters at Grand Central train station gaped Sunday at a 1,502-pound pumpkin on display, the world's heaviest, according to organizers at the Manhattan transit hub.

The pumpkin was on display as part of Halloween charity, and smaller pumpkins were sold to the public for $5 or $10 each, with proceeds going to the Food Bank For New York City, which feeds the hungry, said Karen Weber, a spokeswoman for Grand Central Terminal.

Grand Central, which brought the pumpkins in for the event, bought the big pumpkin from a Rhode Island man for an amount Weber declined to share. The pumpkin was to be donated to the Ulster County Food Bank after the event, she said.

On the Halloween holiday, celebrated on Oct. 31 on the eve of All Saints' Day, American children go trick-or-treating, dressing in costumes and going door-to-door asking for candy or other treats. A jack-o-lantern — a face carved into a pumpkin — is a traditional element of the holiday.

Hugh McMahon used knives to carve the pumpkin for Halloween.

The 52-year-old has carved pumpkins at the Whitney Museum, at the Brooklyn Academy of Music, for the domestic guru Martha Stewart and on "Good Morning America." It took two hours to clean the pumpkin, and McMahon estimated it would take him another five to six hours to carve it.
