Here is a close up of the smaller version of the TWA Rocket. Too bad it is slightly obscured by the tree.
The next shot is of construction of one of the Hotel towers. I believe this is the Bonita tower which opened in 1961 in conjunction with the expanding of the Monorail track. The sign in front of the building is unreadable with the exception of Disneyland Hotel.
And thanks to anonymous for setting me straight, the Sierra Tower was constructed first and then the Bonita Tower came later.
