Czechoslovakian 2.50 Koruny Stamp featuring Praška

This is a rectangular postage stamp from Czechoslovakia, featuring a monochromatic depiction of a significant architectural and sculptural landmark. The stamp's primary color appears to be a dark blue or black print on a light, possibly off-white or yellowish, paper base. The design is framed by a thin black border, and the words 'CESKOSLOVENSKO' are prominently displayed at the top within a rectangular panel, indicating its country of origin. Below this, in a smaller font, the word 'PRAHA' is visible, suggesting the city depicted is Prague. The central image shows a large, classical-style building with a domed roof and columns, likely a significant public edifice. In front of this building stands a prominent equestrian statue on a pedestal, flanked by other smaller sculptural figures, typical of a historical square or monument. The denomination '2 50 KORUNY 2 50' is clearly visible at the bottom of the stamp, with 'KORUNY' (Koruna, the currency) centrally placed between two '2 50' numerals, each enclosed in a box. The stamp exhibits classic perforation around its edges, indicating it was part of a sheet and intended for postage. The visible condition includes some smudging or cancellation marks in the bottom left corner, suggesting it might be used. The color density and fine lines indicate a high-quality printing process, likely intaglio or lithography, common for postage stamps of the early to mid-20th century. The slightly yellowed paper hints at age, placing its estimated age sometime between the 1920s and 1950s, a period when Czechoslovakia existed as an independent nation. The craftsmanship appears to be of good quality, with clear details in the architectural and sculptural elements despite the small scale.
