A、He asked them about his lost paintings. B、He knew the owner of two missing paintings. C、He left his paintings at a highway res

German police appealed Friday for information about the possible owners of two 17th-century oil paintings.
    Police said a 64-year-old man found the paintings in a garbage pile at a highway rest stop last month. He later handed them in to the Cologne police.
    An initial assessment by an art expert concluded the two framed paintings were originals, police said.
    One is a landscape painted by the Italian artist Pietro Bellotti dating to 1665. The other is a painting of a boy by the 17th-century Dutch artist Samuel van Hoogstraten, date unknown. Their combined worth is estimated to be around one million euros.
    Authorities have not yet confirmed what will happen if the rightful owner is not found. Nevertheless, it is speculated that they could either be handed over to the National Art Museum of Cologne or sold to the public by the local government.
