This Day in the History of Hoaxes: July 29

July 29, 1955: The MacNab Photograph
Bank manager Peter MacNab took this photo on a "hazy, warm" July afternoon in 1955. However, he didn't share it with the world until October 1958 on account of "diffidence and fear of ridicule." It quickly came to be considered a classic Loch Ness Monster photo. However, MacNab distributed two slightly different versions of what he claimed was the original negative, leading many (even Nessie believers) to suspect a hoax, because if MacNab did doctor the original image (either painting in the monster, or painting out a boat) he may created multiple "original" negatives during this process.
