Here is a great card showing the iconic Contemporary Resort as well as Monorail Yellow exiting the building.
The Contemporary Tower, the most prominent of the resort’s four stand-alone buildings, was built as an A-frame with outer walls which slope inwards around an inner atrium. This design was a collaboration by Disney, the United States Steel Corporation, and Los Angeles architect Welton Becket. To construct the building, steel frames were erected on-site and modular pre-constructed rooms, designed by California architect Donald Wexler, were lifted into place by crane.

Here is an interesting Youtube video about this wonderful resort.
