One of the most beloved treasures that Del Mar racing fans cherish is their Del Mar Hawaiian print shirts. It’s a festive look at an iconic race track. The shirts do not age. Instead they gain a certain cachet as they are worn. They are considered classic, prime, rare or vintage. When the Breeders’ Cup marketing department started working with Upper Marketing in developing merchandise and apparel for the Breeder’s Cup, they decided that they wanted to create an homage to the famous Del Mar track.
