Description: This 30-haléř commemorative postage stamp was issued by the Czechoslovak Socialist Republic (ČSSR) to celebrate the nation's Third Five-Year Plan. The top margin reads "PLÁN ROZVINUTÉ VÝSTAVBY SOCIALISMU" (Plan for the Developed Construction of Socialism), while the left margin explicitly references the Third Five-Year Plan ("III. PĚTILETKA"). The intricate design illustrates a massive metallurgical plant, highlighting a blast furnace network and structural piping, complete with projected crude iron (surové železo) and steel production (výroba oceli) targets comparisons for 1960 and 1965. Designed by artist František Hudeček and engraved by Bedřich Housa, the stamp features their signatures neatly etched into the lower border margins.
