Saumur - Horse training at the Cavalry School. Saumur is home to the Cadre Noir, the Ecole Nationale d'Equitation (National School of Horsemanship), known for its annual horse shows, as well as the Armoured Branch and Cavalry Training School. This card features a very interesting style of written message, running in two directions forming a lattice effect around the central photographic portion of the card.
