This Polish semi-postal stamp depicts the automobile factory at Żerań (Fabryka Samochodów Osobowych na Żeraniu), highlighting post-war industrial progress. The green design shows a mechanic working on a car being serviced, symbolizing Poland’s efforts to modernize its automotive industry. Issued with a surcharge (45 gr postage + 15 gr charity), it supported social funds while promoting national industry. Designed and engraved by the celebrated engraver Czesław Słania, this issue reflects both industrial pride and early socialist-era philatelic themes. A notable piece for collectors of Polish industry and semi-postals.
