NICE 1890 Chicago Western Indiana Railroad and The Belt Railway Co. legal letter

Description

1st - I AM NOT A BUSINESS AND DO NOT HAVE POSTAL PICK-UPS TWICE A DAY  so please allow me IF needed an extra day or 2 to get to the Post Office.
Sorry but sometimes, not always, the colors are off/yellowish when my is taking picts of bright things.
l acquired a small lot of RARE railroad/railway related and other old envelopes, stamps, ect. and of mostly defunct railroads.
I don't know what any of these pieces may bring but just incase they are actually as rare as I think they may be, I'm keeping my "BUY IT NOW" values high.
I will probably be a way for the long HOLIDAY weekend when this is scheduled to end so please be patient if needed. Thanks!
This is from their law department and not the typical/common railroad ephemera.  Personally, I also really like the watermarks.
PLEASE ask questions and do your research before you bid and BE SURE it is what you want so we don't have to go through the hassles and costs of returning. Thank you.
