In this vintage Tour de France photo from 1934 we see Federico Ezquerra (Spain) who was the first to reach the top of the Télégraphe and the Galibier in this stage. Comments on Flickr suggest the photo was taken at ‘Granges du Galibier’, which means the photo was taken during Stage 7, from Aix-Les-Bains to Grenoble, a whopping 142 miles (228 km)!

If all is true, it means the photo was taken on 10 July 1934. What an awesome shot!
