The celebration of the century kicks off Wednesday as Chicago’s Wrigley Field marks one hundred years.
And what would a party be without a little cake?
Staff and volunteers at the Jewel-Osco supermarket headquarters have been busy frosting and decorating more than ten thousand cupcakes for the celebration.
Some of the crew began early and will work late into the night.
They'll load the sweet treats into two trailers and take them to the park.
Jewel is also donating ten thousand dollars to Cubs charities, one dollar for every cupcake given away on Wednesday.
