manuscript postmark in red with matching "25" rate on 1833 folded letter to Collinsville, Connecticut, additional manuscript "Missent & Fwd", vertical filefold, very fine, an incredibly important piece of Chicago postal history. Only approximately a dozen manuscript postmarks are known from Chicago in the period from 1831 to 1833. Nearly all are in the handwriting of Postmaster John S.C. Hogan, who was appointed November 2, 1832. Chicago manuscript postmarks come to market less frequently than one would expect, and therefore this wonderful example represents a rare opportunity for a collector to acquire one of the key items for a comprehensive city or state collection.  Reference: illustrated in Piszkiewicz (page 2)
