The USPS Still Calls It The "Amoco Building"
Edelman's office in Chicago are in the Aon Center, which started it's life as the Standard Oil Building or " Big Stan " as the locals say and as their brand evolved to Amoco, so did the name of the building. Today, it is now named the Aon Center , but if you go to the United States Post Office on the lower level, you'll be taken right back to the 80's and 90's when Amoco was 'a thing'. They print it on the top of their receipts like the one I got when I bought some stamps there last month.
