The second view is a different angle for the Vitarama show. I like the "weenie" of the large tower and also the cartoon looking clocks. Both were to show up later at Disneyland in similar guises.
The third image shows the New Orleans section of the fair. It does look familiar, especially when compared to the early restaurant row in Frontierland that housed Aunt Jemima's and the Silver Banjo.
The next image is of the display exhibit building for the Chicago and Eastern Illinois Railroad. The theming of the building is nice evoking Florida in Chicago. The famous Bok Singing tower was recreated for this section.
The next set of images are from the "Wheels-A-Rolling" show. Set on a large stage on the shore of Lake Michigan, the show highlighted various trains and included little vignettes to set the time. The first image is a recreation of the driving of the Golden Spike at the completion of the Transcontinental Railroad at Promontory Point in Utah.
The next image is the Harvey Girls section. This vignette featured the famous Harvey Girls serving food to patrons of the Fred Harvey House restaurants. When Walt and Ward visited the fair, Walt was recruited to be one of the guests served by a Harvey Girl.
The next two images show Ward's favorite parts of the pageant, the 1890s featuring bicycles and high wheelers.
And the Roaring Twenties featuring a Keystone Cop like chase.
To see a great scan of the program and for some more images, check out Chicago Railroad Fair 1949.
