After World War II, Rudi Schlattner and his family left their home in Czechoslovakia. He didn’t return for 70 years, and when he did, he discovered something unbelievable. Before Rudi Schlattner’s father left the house, he hid some of their prized possessions in the roof to protect them from being confiscated. The long lost treasures remained there for over seven decades, and when Rudi was able to return, he found them. See the photos of their preserved family treasures below.
