The small piece of concrete inside the postcard contains the story of the whole Berlin Wall and preserves an important part of human history. The sample represents World War II, the cold war, communism and all the individual stories that are connected to the Berlin Wall. It’s a memory of the past for the future. The letter on the right is from the director of the museum thanking me for the gift of the contemporary mineral, including its new location in the permanent collection.
