This is an authentic German Empire postal stationery card issued under the Deutsche Reichspost in 1876, featuring an imprinted 5 Pfennig lilac stamp with the imperial eagle design. The card was postmarked in Wiesbaden on 16 March 1876, with a clear circular date stamp. It is addressed to Herrn August Wolff, Schlossverwaltung, Biebrich a/Rh., referencing the Biebrich Palace administration near Wiesbaden.

On the reverse, a short handwritten message is present, with an arrival postmark from Biebrich (17 March 1876), completing its postal journey within a day. This postal stationery exemplifies the early standardized communication system of the German Empire, combining practicality with philatelic interest.

Collectors value such items for their legible cancellations, complete addresses, and historical context tied to German unification and the rise of Reichspost services.
