Issued by West Berlin (Deutsche Bundespost Berlin) in 1978, this 40-pfennig commemorative stamp depicts a detailed cutaway diagram of an early space shuttle concept, highlighting the onboard orbital laboratory (“Weltraumlabor”). The design reflects Cold War–era European participation in space science and the emerging shuttle program. Printed in deep green with crisp technical line work, it’s a popular thematic item for collectors of space exploration, technology, and German philately. A striking and futuristic issue from Berlin’s late-period commemoratives.
