Make your mark across Chicago with companies such as Arnold, Schwinn & Co., Oscar Mayer, and Quaker Oats. This expansion, which can't be played on its own, also features upgraded, premium card-stock money and wooden tokens to represent all new and base-game companies alike. —description from the publisher
