This was only the second sign to greet guests as they entered Disneyland in the park's 44 year history. The original marquee, erected in 1958, had letters that had to be changed by hand. This sign was updated in the mid-60s and removed completely on October 2nd and 3rd, 1989. The current computer controlled marquee has stood since then welcoming guests to Disneyland in a number of languages and letting them know the park's hours, entertainment and special events.
Disneyland has not yet announced what the replacement sign will look like or where it will be located. Below are some pictures of the sign intact and how it looked on Monday.
