several men in traditional clothing preparing a brown horse for a competition. The horse is being saddled with a brown leather saddle by a man in a white shirt and white pants and a straw hat. Another man in a tan poncho with white stripes is adjusting the horse's bridle. He is wearing a straw hat and has a badge with the number 137 on his poncho. Other men are nearby, also dressed in traditional attire and straw hats. The scene appears to be outdoors in a grassy area with trees and some tents in the background. The weather is sunny.
