Watch Collector's Call Season 4 Episode 6 Online

Driven by his "completist" mentality, Kevin Hermann has built an impressively vast collection of movie props and costumes from his favorite films - including one of the most complete costume collections from the hit franchise, Underworld. Kevin collects what he loves - from rare Indiana Jones and the Temple of Doom props to the original puppets from the animated series, Gumby - and that love has turned into a hefty investment. Expert Mark Short places a seven-figure value on Kevin's massive collection. With Kevin's appetite for complete costumes - including the accessories - Mark comes prepared to trade two costumes and a prop from a popular television series in hopes of taking home one of Kevin's more gruesome rarities.
