The White Pine is a seeding of the largest white pine in America, located in Nicholet Park, Wisconsin. The tree, donated by the Living Museum of Trees, was grown from one of the last pine cones produced from the one-thousand-year-old parent tree named for Douglas MacArthur in 1945.

There are many examples of military uniforms, including original Civil War uniforms, nurse uniforms, military weapons including ammunition, newspaper articles, etc.

During World War II, James Allison, a sports writer for the Houston Press, saved war images that were not printed in the paper and amassed over 4,600 photos of the war. Allison donated these photos to the Arkansas Museum of Science and History in August 1977 and they are now displayed in this museum as well.

General Douglas MacArthur returned to Little Rock for the first time since his birth on March 23, 1952 at the age of 72. He had been relieved of command by Truman a year earlier. On his return trip, he went to the church where he was baptized in 1880, Christ Episcopal Church in Little Rock. 25,000 people greeted him at that time. He only spent about a half day in the city before he left for New York.
