Czechoslovakian 50h Jan Evang. Purkyně Postage Stamp

This item is a historical postage stamp from Czechoslovakia, featuring a portrait of Jan Evang. Purkyně. The stamp is predominantly grey-green or dark grey in color with a lighter background for the portrait. It is rectangular in shape, approximately 35mm x 25mm (estimated based on typical stamp sizes), with perforated edges on all four sides, indicating it was part of a larger sheet. The central image is a left-facing profile bust of Jan Evang. Purkyně, depicted as an older man with distinct facial features, a high forehead, and a noticeable nose. He is shown wearing what appears to be a collared shirt and possibly a jacket or coat. Above the portrait, prominently displayed, is the country name 'CESKOSLOVENSKO' in sans-serif capital letters. Below the portrait, to the left, is the denomination '50h' (50 hellers), and across the bottom, neatly aligned, is the name 'JAN EVANG. PURKYNE'. The overall artistic style suggests a period likely mid-20th century, possibly commemorating a significant anniversary or historical figure. The condition of the stamp appears to be uncancelled, with crisp perforations, though there might be some slight discoloration on the surrounding paper margin, which is a light buff or cream color. The printing quality seems fine, with clear lines and good detail in the portrait. There are no obvious tears, creases, or major visible condition issues on the stamp itself, suggesting it is well-preserved. There are no clear visible manufacturer's marks or signatures, which is typical for postage stamps of this era.
