Seattle Slew became the 10th horse ever to capture racing's Triple Crown in 1977 when he waltzed through the gauntlet of the Kentucky Derby, Preakness, and Belmont Stakes. Until Justify turned the trick this season, Slew was the only horse to have won the Triple Crown while undefeated and took down Horse of the Year honors in 1977. This horseshoe was worn by the potent stallion while standing stud at Spendthrift Farm in 1984. That year, his son Swale won the Kentucky Derby and Belmont, which propelled Slew to leading sire status. His influence is still pervasive today through his son A.P. Indy, who is a foundation sire for many of racing's contemporary greats. The horseshoe is mounted on a wooden plaque with a smaller gold plaque at its center engraved "Seattle Slew," and a small photograph at top, measuring 8x10" in all. It comes from Wes Lanter, who was groom at Spendthrift from 1983-86, and comes with an LOA from Lanter. In the Blood-Horse magazine List of the Top 100 U.S. Racehorses of the 20th Century, Seattle Slew checked in at ninth.
