A crisp black silhouette profile of Queen Elizabeth II anchors the top left corner. Running vertically along the lower right-hand margin is the black inscription "Millennium 1999/3 / World of music/B Riley," positioned directly over the numeric denomination "26." This pristine, uncancelled mint specimen features highly uniform perforation edges on all four sides.
