This rare German local issue features a brown Stadt Omnibus (city bus company) revenue stamp valued at 2 Pfennig. Such stamps were privately issued by transport companies in the late 19th and early 20th century for bus fares in German cities. The design is ornate, with bold numerals in the center, decorative framing, and inscriptions identifying the issuing omnibus company. The stamp bears a central punch cancel (commonly used for ticket validation) along with an additional circular date cancellation. Local revenue/ticket stamps like this were never officially postal but hold high interest among collectors for their rarity and insight into urban transportation history.
