This early Polish definitive stamp, denominated 5 marek, features the historic White Eagle, Poland’s national emblem, framed within an ornate heraldic shield. Issued shortly after the restoration of Polish independence, it belongs to the first definitive series of the Second Polish Republic. Printed typographically in a deep reddish-brown shade, these stamps are known for their coarse wartime paper and variable perforations, making well-centered, cleanly perforated examples desirable. Postmarked copies remain popular among collectors of early Poland due to their strong historical context and distinctive classical design.
