The US Postal Service and the Principality of Monaco jointly issued commemorative stamps on March 24, 1993, in Hollywood, California, and Monaco, to honor Grace Kelly, Academy Award-winning American actress and princess of Monaco.
The US and Monaco stamps were based on a photograph of Grace Kelly from the film "Country Girl" (1954), the film that won her an Academy Award. The stamps are identical except for the denomination, country name, and inscription. The 29-cent US stamp inscription reads, "Grace Kelly." Monaco's stamp reads, "Princesse Grace," and sold for 5 francs ($1.00 US currency at that time).
Grace Kelly made her film debut in "Fourteen Hours" (1951). Other notable films include "High Noon" (1952), "Mogambo" (1953), "Dial M for Murder" (1954), "Rear Window" (1954), "To Catch A Thief" (1955), and "High Society" (1956). Kelly retired from the film industry on April 19, 1956, after meeting and marrying His Serene Highness Rainier III of Monaco.
Designed by world famous engraver Czeslaw Slania of Sweden, the stamps, which were issued in panes of fifty, were single-color engraved through the intaglio process by Stamp Venturers, Inc.
