Analysis of information sources in references of the Wikipedia article "Great Rose Bowl Hoax" in English language version.
The single original color photograph of the live prank, a Kodachrome slide, has just been donated to the Caltech Archives, along with full documentation of how the stunt was executed, thanks to the tireless efforts of alumnus and Lloyd man Lee Molho (BS 1963). [...] The donation from Molho and Whitehead includes artifacts and documents that reveal the full story of how the prank was carried out. They will form the Great Rose Bowl Hoax Collection at the Caltech Archives.
Monday evening I got a note from Shelley Erwin, head of the Archives and Special Collections at Caltech, telling me that the original Kodachrome slide had been tracked down and donated to her archives, and pointing me to its online story: "The photographer, Bruce Whitehead, had just arrived in Pasadena to take up a research fellow position in physics. He got a ticket to the game and a seat on the 50-yard line through his father, a Rotarian with connections to the committee that oversaw the annual Rotary float for the Rose Parade. He just happened to be aiming his camera in the right direction as the cards flipped up into position. Whitehead loaned his slide to Caltech's Public Relations office, and a black and white photo of the prank was published on the cover of the January 1961 Engineering and Science. Whitehead then put his slide away for 52 years. Not until he was tracked down recently by Lee Molho and agreed to donate the slide to Caltech did his original see the light again."
