Bizone 1948 Posthorn with Upside-Down Overprint

Germany (Bizone) · 1948 · 48 Pfennig

The stamp features a stylized posthorn design, a common motif for definitive issues of the Bizone. It bears an overprint '48 Pfennig Deutsche Post', which is notably printed upside-down, indicating a significant printing error.

Issued in the Bizone, the combined British and American occupation zones in post-WWII Germany, this stamp reflects the administrative period before the establishment of the Federal Republic. The upside-down overprint is a significant philatelic error from a time of political and economic reconstruction.
