Classic official Dienstmarke (Service Stamp) from Bavaria, issued for governmental and administrative mail use rather than public postage. Printed in deep blue, it features the ornate Bavarian crowned coat of arms supported by heraldic lions, a striking symbol of royal authority. The bold “DIENSTMARKE” inscription clearly identifies its official function, making it popular among specialist back-of-the-book collectors. Crisp line engraving and strong typography give the design a powerful early-20th-century aesthetic. A desirable piece for Germany States, official issues, and heraldry-themed collections.
