EC Archives: The Vault of Horror #1

Henry was jealous of his artist friend Robert for not selling his etchings. One day Henry began selling Robert's work to an art buyer. Robert found out and confronted Henry, who threw acid in his face then dumped the body into an acid vat. Henry almost used up the wealth of Robert's drawings until he met a wax statue maker and opened a museum with him. When one of the statues' arms was damaged Henry found a human hand beneath it. Henry confronted the sculptor, who removed a wax mask from his face, revealing himself as Robert.
