Harry S Truman Presidential Library & Museum

There are thousands of objects, including the famous "The Buck Stops Here!" sign, from the man who led the US through one of its most tumultuous eras. More than that, the museum provides a vivid snapshot of America in the late 1940s and early '50s. The museum reopened in 2021 after a $29 million transformation to make it more relevant and engaging to the politics of today.
