This week we are hoping to identify this show jumper from 1967.

President Éamon de Valera is pictured presenting a trophy to a champion rider at the Dublin Horse Show in the RDS on 11 August 1967. But who is the rider?

If you think you can help, please contact us at archives@rte.ie or via Twitter @RTEArchives.

Also pictured is de Valera's aide-de-camp Colonel Thomas McNamara.
