World's Fair Parade
From Teresa Moller:
"The four images are all 8 x 10s which appear to have been taken around the time of 1939 World's Fair. The backs of two of the photos (#'s 1 and 2) are stamped "International News Photos"."
The 4 photos have been identified and are now located at "Howard Huges Fair Flight"
Thanks to all that helped identifying the images.
