Memorial Project for Jobbers' Canyon Built with ConAgra Products pays homage to lost architectural treasures. In 1989 ConAgra, the second largest agricultural distributor in the United States, began building its new corporate headquarters in Omaha, Nebraska. In the process, twenty-four buildings over six city blocks were demolished. The district, known as Jobbers' Canyon, was listed in the National Registry of Historic Places and is considered the largest lost site on record. Using preserved records and architectural drawings O'Brien has 'rebuilt' ten of the buildings, substituting the original construction materials with products distributed by ConAgra.
