Rob Purchased an Old Glass Vase, Which Banya Represented as an Antique

Rob purchased an old glass vase, which Banya represented as an antique made by a famous Italian glassmaker in the 17^th century. As proof of its authenticity, Banya produced an old paper with a rough sketch of the vase on it, along with some writing, and what appeared to be the glassmaker's name. Rob later sold the vase to Castillo, after telling Castillo the story of the vase as told to him by Banya. After Castillo had purchased the vase, he discovered it to be a reproduction of the original, and of very little value. The contract is voidable by Castillo on the basis of innocent misrepresentation.
