Japanese 6 Sen "Kiku" Chrysanthemum Postage Stamp with Postmark

This item is a Japanese postage stamp, likely from the 'Kiku' (Chrysanthemum) series, featuring a prominent imperial chrysanthemum crest at its center. The stamp is predominantly red-orange in color, with a faint, intricate background design that appears to be pattern-based rather than a specific illustration. The numerical denomination '6' is visible in a red rectangle at the bottom left, accompanied by what appears to be Japanese characters for the denomination in the center bottom. The letters 'SN' (likely 'Sen') are also visible in a red rectangle at the bottom right corner. The stamp itself is rectangular with perforated edges, indicating its primary function as a postage stamp. It bears a heavy, circular black postmark that partially obscures the central design and the top left corner. The postmark clearly displays the date '11.10.27', written in a Western numerical format, which likely signifies the 11th year of an imperial era, 10th month, and 27th day, consistent with Japanese dating conventions of the early 20th century. Below this date, there are additional characters that are less clear due to the postmark's density, but they seem to indicate a location or further postal information, with some characters appearing to be 'ヒ4-8'. The corners of the stamp and the perforations show some wear and slight rounding, suggesting handling and age. The paper quality appears standard for postage stamps of its era. The heavy postmark indicates it was used for mailing, and while it confirms authenticity of use, it also affects the visual clarity of the stamp's underlying design. The style suggests it dates from the Meiji or early Taisho period in Japan.
