I bought a photo off of ebay a couple of years ago, it was described as "woman and children at the Disneyland Hotel". When it arrived in the mail, I realized that the woman was Shirley Temple. I did a search on the internet, and found the other two images of Shirley at the rededication of Sleeping Beauty's Castle on April 19, 1957 I'm really glad I saved them at the time, because I can't find them online now. There beside her are her children...oldest daughter Linda, son Charles, and youngest daughter Lori. You can see in the photo with Walt that they are wearing some of the same clothing as the hotel tram picture. I believe that this is when the castle "walk-thru" was added, with its dioramas illustrating the story of Sleeping Beauty.
Back in 1939 (February 7th), Shirley had presented Walt with an honorary Academy Award (one big Oscar, seven little ones) for "Snow White and the Seven Dwarfs". So it was a nice reunion for the two of them! Shirley went on to host a few television shows ("Shirley Temple Theater", for example), before embarking on a successful career as a diplomat and ambassador.
