In which year was "land" removed from the original "Hollywoodland" Sign?

The Hollywood Sign is an American landmark and cultural icon overlooking Hollywood, Los Angeles. Originally the Hollywoodland Sign, it is situated on Mount Lee, above Beachwood Canyon in the Santa Monica Mountains. Spelling out the word "HOLLYWOODLAND" in 50-foot-tall (15.2 m) white uppercase letters and 450 feet (137.2 m) long, it was originally erected in 1923 as a temporary advertisement for a local real estate development.

Due to increasing recognition, the sign was left up, with the last four letters "LAND" removed in 1949. The sign was entirely replaced in 1978 with a more durable all-steel 45-foot-tall (13.7 m) structure and concrete footings.

Among the best-known landmarks in both California and the United States, the sign makes frequent appearances in popular culture, particularly in establishing shots for films and television programs set in or around Hollywood.
