The whole article:
“FLYING SAUCER?—These pictures were taken by Warren Siegmond from the roof of his Manhattan home May 15 (1955). Mr. Siegmond, a TV technician, was ready to photograph Jeannine Bouiller of France when the model gasped and pointed skyward. Mr. Siegmond noted the spherical object and made several pictures before it disappeared. He served from 1943 to 1945 with an anti-aircraft battalion in England. The pictures were first published by The New York World-Telegram and Sun.”
The Pittsburgh Press presents two of the UFO photographs. One of the photos seems to show that the UFO is self-luminous.
