At the 1964-1965 New York World's Fair: This is part of a slide program I shot during the two years of the Fair. The camera I was using then was a Rolleiflex T, which uses 120 film. The film was all High Speed Ektachrome, which has lasted through the years in excellent condition. I started this as a photo preservation project. These are two of only three in the entire 160-picture set that are with a railroad subject.
