Issued by Deutsche Bundespost Berlin in 1978, this dynamic 40-pfennig stamp commemorates the III Swimming World Championships held that year. The design captures the fluid motion of freestyle swimmers in action, their red caps contrasting vividly against blue water and yellow lane dividers. The modern, stylized depiction emphasizes speed, strength, and international athleticism. A striking example of late-1970s German graphic design, it celebrates Berlin’s connection to global sporting events and athletic excellence.
