Czechoslovakia 1920 Hradcany Surcharge Issue Postage Stamp, 25h on 50h, Lion and Chain Design

This item is a vintage postage stamp from Czechoslovakia, specifically from the 1920 'Hradcany Surcharge Issue.' The stamp features a monochrome design, likely in a dark brown or sepia tone against a lighter background, possibly cream or light grey paper, indicative of its age and printing process. The central motif is a stylized, heraldic lion, depicted dynamically with an ornately flowing mane and tail that twists into decorative flourishes. The lion appears to be breaking free from or interacting with a heavy chain, which is visible wrapped around its body and extending towards the foreground. Below the lion, on the left side, is a prominent circular or oval cartouche containing the denomination '25' followed by what appears to be a smaller 'h' for 'haleru' (heller), indicating a surcharged value. The top border of the stamp clearly displays the text 'POSTA CESKOSLOVENSKA' in capital letters, signifying its origin. At the bottom left, the faint inscription 'J. OBROVSKY' is visible, identifying the artist or engraver. The stamp exhibits classic perforation around its edges, although the specific count is not discernible from the image. The overall condition appears to be relatively good for its age, though minor wear or slight discoloration consistent with handling and storage within an album is possible, given its presentation. The intricate details of the lion, the elegant script, and the art nouveau-like elements in the design point to a high level of craftsmanship. The reverse side is not visible, so gum condition or watermarks cannot be assessed. This stamp represents a historical period following the establishment of Czechoslovakia as an independent state, and such issues often hold cultural and historical significance beyond their postal utility.
