What are the Cottingley Fairies?
The Cottingley Fairies are figures that appear in a set of five photographs taken by cousins Elsie Wright and Frances Griffiths in 1917 and 1920. Today, the Cottingley Fairies are widely considered a hoax. However, at the time they were taken, the photographs had a number of believers, including Arthur Conan Doyle, the creator of Sherlock Holmes.
