The Los Angeles-based Julien's Auctions house is currently accepting bids on a serving of the couple's wedding cake, which was originally provided as a take-home souvenir for guests of their January 2005 nuptials, Fox News reported on Friday.
According to Julien's, the couple actually displayed an altogether different cake at their reception - a seven-tier, 200-pound confection made with Grand Marnier buttercream frosting and decorated with 3,000 icing roses - though it "was not eaten by the wedding guests due to the amount of wire used to make it stand."
Instead, the duo doled out individual chocolate truffle cakes in white paper boxes. The portion up for auction, too, will be housed in the same paper box.
The auction house estimates the serving will sell for between $1,000 and $2,000.
A sketch he drew of the Empire State Building sold for $16,000 last month, and another doodle of the New York City skyline went for $29,000 in July.
The official auction for the cake commenced on November 17.
