Hello Everyone,
I have this cover

This cover stopped in Chicago on Sept. 26 at the Registry Division, then on the 27th at the Old Post Office Station and then on the 28th at Fort Dearborn Station. I was wondering why it would go to the "Old Post Office Station?" I have many covers with the Registry Division marking along with Fort Dearborn Station or ones that have just the Fort Dearborn Station marking on them and I was wondering if someone might be familiar with or have an explanation as to why the additional stop was needed. Also, is the post office located on a street named "Old" and thats why it's name is Old Post Office Station?
