The Andy Warhol Museum of the Modern Art in the town of Medzilaborce, Slovakia, is missing two major works by Andy Warhol. A loan was made to an individual who has vanished, along with both the paintings, since March.

Slovak police are investigating. One of the missing works is from the Pop artist's famous Soup Can series. The other work is a popular image of Marilyn Monroe.

Deputy manager of the museum Michal Bycko stated: "The artworks which were loaned were collected by a security company with guns. They had all the relevant documents so there was no reason not to hand them over."

Near the artist's mother's hometown, the museum holds 160 Warhol artworks and memorabila, making it the second largest collection of Warhol’s artworks worldwide after Pittsburgh’s Andy Warhol museum.
