Okay, some early Olympic suggestions;
Ellen Hoog (women's field hockey) -- I'm pretty sure any orange memorabilia cards would sell pretty well; Dutch field hockey team
Dana Vollmer (swimming) - looks to have a great Olympics
Kim Rhodes (rifle) - maybe not a great $ choice and she is in Topps Olympics set, bet medaling in 5 straight Olympics is the definition of a Sportking.
