A page from The Illustrated London News showing a diagram by unknown photographers, comparing a single-exposure race finish to a photo finish. The race pictured is the finish of the Oaks at Epsom on 8th June 1962, in which the French horse Monade beat West Side Story by the narrowest of margins(hotly followed by Irish horse Tender Annie). The context victory was settled using a photo finish print of the event, the lower image on this page.
