The design features a delicate silhouette of a woman reading a letter, framed within an ornate oval wreath and topped with a ribbon. The soft green and black engraving evokes elegance and nostalgia, symbolizing communication and the art of correspondence. A fine example of postwar Polish design blending simplicity and symbolism, this issue remains a cherished piece among collectors for its aesthetic and thematic value.
