In 1963, when the sculpture of The Little Mermaid, situated in the harbor of Copenhagen, was about to celebrate her 50th anniversary, The Tourist Association of Copenhagen (Wonderful Copenhagen) chose Ib Antoni as the designer of the official jubilee-poster.
On purpose, Ib Antoni has drawn The Little Mermaid very large in comparison to the smiling tourist, maybe to emphasize how big she is in the eyes of the visiting tourists.
