Those items include a Civil War-era battlefield map of Gettysburg, Pennsylvania, that measures four meters square and a bathtub modeled after the one made for President William Howard Taft, the largest U.S. president. He weighed about 145 kilos (320 pounds). "There were a series of items that were custom made for him, including his bed," says Johnson. "We have a telegram where it is asking for a bathtub, listing the dimensions and describing it as 'pond-like.'"
