In the Competition Riders section of HHO, ‘tonkatoy’ posted this fantastic find. There are thousands of old photos by Kit Houghton.
The Search function is pretty good (someone did a lot of work cataloguing these photos correctly), so you can put in the name of a horse or rider and bring up lots of pics of them, from the ’80s to the present day (this year’s Badminton photos are included). There are some misplaced photos but still loads that are easy to find.
Of course all photos are Copyrighted, so they are not to be stolen, but it’s fun to see the huge questions and how the horses and riders coped with them. There are questions there that we’ll never see again…!
