Wow, rare ephemera. I'm trying to figure out what it says. So far I've got:
First Nat Bank
Cassopolis M. [?] [?]
Enclosed some of our Blank Receipts - Mr howe requested Several (?) parties to pay you. You can remit in [?] of not less than 10.00 NY Drafts - payable to [?]
Yours [?]
N. G. Cooper for The (?) Howe M Co.
The capricious capitalizations of Mr. Cooper are not helping to decipher this. Sometimes I wonder how stuff like this got saved and then unearthed after 130 years. After my mom passed away I found ALL the records from my father's business, from the mid 1940s through 1980, in the basement of her house. Every letter received, carbons of every letter sent, every invoice, every brochure, everything. I love ephemera so it was overwhelming. I did save a few things but I had to trash most of it. Never did find my birth certificate, though.
