Photographs and Background on Unidentified Flying Object Seen by Ralph L. Mayher
A CIA memorandum accompanying photographs and background on an unidentified flying object seen by Ralph L. Mayher. The print marked "A" is an enlarged photograph of the original 16 mm movie strip on which Mayher took nine photos in 1952; the size of the object may be gauged against the standard perforations on the film. The large print marked "B" is an outsized enlargement made from a stepped-up negative of one of the original frames.
