I didn't realize it at the time but this detail from http://SWC-Biogon.smugmug.com/photos/191494492_f6Bgc-L-2.jpg shows the "OZ" prop, scene graffiti and the set crew moving a taxi prop. It wasn't until years later, when I picked up a DVD of the WIZ that I took a closer look. October 15, 1977.
Detail shows one of the WIZ graffiti characters from which a real actor would emerge during the film.
View down the "Sky Streak" elevator cables to the interior of the second level doors. October 15, 1977.
