Representing some of the greatest sires in the world, offered here are stallion halters from Distorted Humor (sire of Kentucky Derby and Preakness winner Funny Cide, as well as Belmont Stakes and BC Classic winner, Drosselmeyer), Maria's Mon (sire of Derby winners Monarchos and Super Saver) and Medaglia d'Oro (sire of Preakness winner Rachel Alexandra). All three halters come with COAs and the Medaglia halter has a misspelling ("o" instead of an "a").
