A series of photographs, probably taken by a student in the early 60s, looking down into a ride where the floor drops out and the riders are kept in place by centrifugal force. Most were Kodachrome and Ektachrome slides with some black and white prints mixed in. Full Disclosure: while I don’t normally do anything more than clean dust off of the photos in this case I did some very basic color adjustments to the faded Ektachrome slides.
